Why do you pay half the bills? There are 3 adults and 1 child on his side and 1 adult and 1 child on your side. This should not be a 50/50 split.

It is not fair to your 5 year old to have to live with someone who is constantly picking on her. Either DH needs to control his daughter, or you and your daughter need to move out. Date this guy if you want to, but don't continue to make your daughter live in a situation that is not safe and comfortable.

Kind lady this has to stop now.

Like the comment above you should NOT be paying 50/50! Its MR. Ihave3biatches  responsibility to cover that. Well actually two are adults so WTF!

Your five year old does not deserve to grow up in an environment where she is bullied especially by a teenager. F that if your oh so loving partner was a good partner and decent dad NONE of this would be happening.

Stop driving ingrates anywhere. I dont give AF if they are minors thats not your responsibility. Do not do for rude lil B's . Your 5 yr old gets picked on rain hell on the skid.

Your partner is taking advantage of you. How nice for him that you pay bills for his spoiled B's. You deserve better and so does your daughter.

Does he stand up to them. What does he do when his spoiled shits are rude to you? Even bigger question does he intervene when the SD13 picks on a FIVE YEAR OLD?!  Im livid writing this.

Blessings

The 13 year old keeps removing my things especially my daughters school photos. I always hear "dad's house" "dad's bills" but I'm sorry its mine too. I'm sick of being invisible. I clean and nobody notices. I cook they don't say thank you.

What does your partner DO about it? If she KEEPS removing your things, then any punishment/consequences isn't working. Does your partner correct her when she says "dad's house?" Does your partner notice that you clean and cook and thank you when his children are around? 

Your 5-year-old should not have to live in a household where she is actively disliked. How is your partner addressing THAT with his daughter? Repeatedly telling your daughter to ignore his daughter is not a solution. Your daughter's experience is that it's ok for her to continue to be the target, and she will grow up with that and likely accept that bad behavior is normal, or normal toward her. She needs action, and that's YOUR job to ensure she gets it. Where's your Mama Bear?

Frequently we see bad behavior because the bio parent allows it.

If you're paying half the bills then he obviously needs you a lot more than you need him. You need to talk to your husband about his kids showing you and your daughter some respect. It's your home too and if they don't start acting like it I think you seriously need to consider. It's unacceptable for a teenager to be picking on a five-year-old.

what would you do to protect your child if there was a bully in school, on the playground? the bully is in your home and it is your job to protect her. Call that crap out. Stop driving them. Start planning for 'what if' because if he doesn't step it up, I hope you prepare to get your kiddo out. asap.

I mentally slammed on the brakes when you said you pay HALF the bills!! Oh, hell naw.

He and his brood represent 2/3 (4 of the 6) and you and your daughter are 1/3 (2 of the 6 people). The only thing you should pay 1/2 of is the rent because you have to live somewhere and would likely pay more if you were renting a place for just you and your daughter, but that's where that ends. For housing costs, it should be split based on income. For instance, if you earn 60K a year and he earns 40K a year, you split the housing costs (rent or mortgage) based on the percentage of the overall household income you earn. In this case, you would cover 60% and he would cover 40%. Your case may be different if he earns more than you.

Anything affected by consumption (food, energy, water, etc.) is paid for based on how many of YOUR people are using it.

You only pay 1/3 of the food, water, gas, electric, cable, etc. You pay YOUR phone bill and car insurance.

Stop paying 1/2 of all the bills, my dear girl.

No comment on the rest, but I'd be all over that 13 year old taking stuff that doesn't belong to her. If her dad doesn't pull her up, he never will and this will go on until you can't stand it any more.

I can't get over telling a 5 year old to ignore bullying and to not rise to it. I'm 57 years old and in therapy and I was literally traumatized from being bullied as a child. My idiot mother didn't know what to do, so she'd just say that kids are cruel or that it's my turn and that next year the kids will pick someone else. I also heard all the bullshit, "rise above it" or "hold your head up high..." Perhaps you would benefit from doing some research on bullying and the long-term effects of bullying and being sold out in your own home as a child. Your number one role is to protect your child. Get her out of there. You can always try going nucking futs on your weak SO for allowing his spawn to bully a 5 year old and that changes are required before the sun sets today or you'll walk. 

"The 13 year old keeps removing my things especially my daughters school photos."

How does your SO react when you tell him about this?

"I always hear "dad's house" "dad's bills" but I'm sorry its mine too."

I do hope you correct her when she spouts this kind of crap.

"I'm sick of being invisible."

It's time you had a long chat with your SO about his daughter's lack of respect for you. This is serious stuff. She doesn't get to ignore you. He needs to ensure this nonsense stops,  like yesterday.

"I clean and nobody notices. I cook they don't say thank you. I drive them places when he's not available and they are so ungrateful."

So stop doing it. Just stop. They should all be sharing the chores and the cooking. There's no reason for you to be the household slave. You work too. Time to draw up a list of chores and allocate them. Are the two eldest SDs paying rent at least? If not, why not? 

"But if I stop I feel like I'm letting my partner down as its helping him too."

Time to get over that guilty feeling - it's outdated by a certain number of decades. It is helping nobody if you are running after them, it is only enabling their lack of manners, consideration and respect. So stop it NOW. Disengage. Take care of yourself and your daughter - the rest is up to him. Oh and, I absolutely agree with the other posters that you should absolutely NOT be paying 50% let alone doing 100% of the donkey work.

"The 13 year old has recently got really jealous and seems to pick on my 5 year old alot because of her age."

This is a biggie. How does your SO deal with this? If he won't deal with it, tell him that you WILL. His daughter is nearly THREE times the age your daughter is and probably much bigger. How can anyone allow this to happen? Stop telling your daughter to deal with it and start going EFFIN' NUCLEAR on his brat when she starts on your daughter. How is it OK for a teenager to bully a little kid? 

Step up and insist on being treated like the lady of the house and not the skivvy. Stand up for your daughter. Stand up for your finances. You are being used, lady and your child is being abused. She should be your number one priority.
