You've only with him for about 2 months.  That is the time when most normal people put their best foot forward.   If this is his best, then he isn't the one for you.  

He may be a great idea as far as dating and hanging out goes.  But he is showing you that he is an awful parent and living with him won't be that great.

My advice would be to throw this one back and find a man who can parent his kids, or better yet, who has none.  Seriously, if he's this lax of a parent, you will be miserable.

Your boyfriend needs to address the issue about them jumping on you, If this is an issue for you. 

2 months in they might be a bit ‘excitable’ when you, or visitors are around. 

I would just go on dates for at least the first 6 months to avoid all this personally. 

They are still quite young and probably more interested with playing with toys than tidying up.. I have only met a handful of kids over the years that willingly tidied up at that age. The only three year old I have known that willingly tidied up as routine, their father had OCD! I don’t think they are too much different at four. 

I used to ‘help’ my two tidy up when they were little and it wouldn’t take long between us all. 

It’s time to sit down and think what you want for your future, and whether this man is worth it. 

You are going to hear this about 50 times on this forum.  Run.  Get out now.  It's not going to get better.  If this works and you get married those kids are going to be running your household and your bf/'husband' will think it is ok.  Throw in a baby, and you will have a child who is influenced by these feral children who are the half siblings.  Get a divorce and your child will still be going to the house of your now 'ex husband' and his feral teens who maybe do drugs while your little guy or girl is there.  Stay on this forum.  Read the stories of women trapped in stephell who saw the red flags but got married and had a baby with these fools who do not parent their children due to post divorce guilty daddy syndrome also called Disney dads.  Every day is a trip to Disney World.  Keep reading.  These kids will not get better without proper parenting and you are not the one to parent them as it will only cause resentment between you and your boyfriend who thinks his kids are just adorable.

1.  Be on birth control

2.  Read thru this site.

You have bern warned.  I'm making a joke. But really, read thru this site and you'll see many folks who have experienced the exact same thing.

Good luck to you.

You think children are born knowing how to be well adjusted members of society? They aren't. It takes work and effort and patience and tons of repitition. You need to keep on at them until they behave themselves and do not answer back to other adults. You teach them to keep their hands to themselves and respect other people's space.... hang on. I forgot. These are not your kids. They belong to this amazing man who allows his sons to hit you, jump on you, answer back, make messes and will not clean up. 

Your BF is a reject. He is not amazing. It is not a difference because you don't have kids, It is about him not being a good father, In fact he is a neglectful father, He is a loser. He allows kids to hurt you. He does not discipline his own children. Obviously his home is Camp Dad. I fele sorry for their mother having to deal with unruly kids after their Dad Time,

This is not the kids fault because kids only LEARN from example and direction. Or does your BF of 2 months (and you are already having sleepovers with the kids there) think WWE gives excellent examples of how to behave? I am not being judgemental about your sleepover status but remember if he let you meet his kids inside 2 months, how long before the next woman comes into his life and faces the same mess?

I'm sorry you feel judged.  I have felt judged before until I realized everyone was right.  I've been married two years and I am looking for the door.  Everything that everyone has been saying to me for the 18 or so months I have been a member of steptalk was so spot on.  I thought things would get better and that my DH would support me because he loves me and he said he would support me when it comes to the kids.  I have been stabbed in the back more times than I can count.  He gets defensive when I say anything to the kids, he gets defensive when I don't talk to them.  THere is no winning with a Disney dad.  He never believes anything I say about them unless I have physical proof.  I told him I want to get camera for my own protection because he doesn't believe me unless like I said I have physical proof.  I'm waiting for the day that one of the skids accuses me of something and these 4 skids are close so they would lie for each other.  My only chance is with a camera.

If you want this relationship to have a chance, maybe try giving your BF a chance to fix it. Think about what behaviors you have a problem with, what are your deal breakers, and what you would like to see more of. Blatant disrespect and cosleeping would be deal breakers for me, but everyone is different. 
 

Have an honest conversation with your BF. If he agrees that these are issues but just feels he needs help or permission to parent properly, there's hope. The rules have to come from him, though. You can assist in enforcing but it can't be mostly you. The other posters are right in that if your BF starts to look at you as the primary disciplinarian, he will likely despise you for it in the end. 
 

I'm about where you are at, except 2 years in amd i have biokids of my own. Not living together. I would say we are about 75% there. It's been a long, hard road. Issues with BM enmeshment, cosleeping, and behavior issues. I've cried, begged, and had countless panic attacks.  
 

At 2 months in, as a childless woman, are you sure you want to deal with this? maybe what you see as "amazing" is your BF's potential. You see how patient and loving he is with his kids. But remember, they will never, ever go away. Even if you get married and have a baby with this guy, they will always be nearby, having some type of influence. Plus, BM may come back and make herself a daily presence in your life if your BF isn't good with boundaries. 

With only two months into this relationship, you really need to look long and hard at what a life with these kids would be like while it would still be relatively easy to walk away.  Your boyfriend might be a very loveable guy, but he's not being a good parent.  He needs to discipline his children and bring them up to be likeable, respectful and well behaved.  If he had done so, you likely wouldn't dislike being around them so much.  I think all you can do if you want the relationship to work out is to talk to him and let him know your thoughts on the matter.  If he responds with the typical "you hate my kids" or "they're only children" or something of the sort, it's time to head for the exits.  If he takes your thoughts to heart, then you can wait around and see how things develop.  But if he doesn't seriously up his parenting game and you stick around, you'll be in for a miserable 14 years until they're launched.

It is way inappropriate for you to be sleeping over while his kids are there two months into a relationship... I don't care if you've known him for 10 years. I can't even go into what that says about his standards or his boundaries, both of which are really important in a relationship with a guy who has kids.

I guarantee his kids are unruly because he is overwhelmed, which begs the question: does he want a girlfriend or someone to help share the burden of these kids. My guess is the latter.

If you want to see if he's really amazing, take a step back, tell him you want to just have fun dates that do not involve kids. Explain to him that if he wants to be with a child-free person, he needs to know how to give her the same kind of courtship you would have with a child-free guy. Also explain that if things go well with the two of you dating one-on-one, the kids will need to be better behaved for this to work. I would say that phase should last about six months. That gives him time to get his ducks in a row at home and you get taken out on a bunch of fun dates in the meantime. If he can do both of those things, then you can start thinking about the next step. (He probably won't be able to do those things, BTW.)

^^^^ This is so spot-on.  You shouldn't be sleeping over there.  Just go back to dating the guy and set your boundaries.  No dates involving the kids; you're not going over there any more- he has to come to you. If he's not willing, find a man without kids or knows how to parent them. Stop being a booty call. Set your standards higher and get away from this mess.  It will not get better. Listen to these people who are telling you this. 

I see a lot of similar situations on this site. Single girl meets a guy whth the kids but instead of him properly dating her and him making an effort, within few months if not sooner, she goes to his house to sleep there and provide him with a booty call and then eventually cook and clean for him and be unpaid babysitter. Whatever happened to dating? You sleep there "every night". That's too soon and too much 

I recommend you stay in your own house. Don't go to his at all. See if he is going to make an effort and arrange nice dates and come get you for dates etc If he really seriously cares about you, he'll do that.
 

But something tells me relationship will not survive if you stay in your house as he doesn't want to make any effort neither with you nor his kids. He wants you to show up without him making any effort and crawl into his bed every night and he expects his kids to raise themselves. He is not a catch. You can do better
