I'm a 27 year old mother to two boys.My sons father and I have been on and off for nearly 7 years main reason being he basically teases me in front of his 3 daughters who also laugh at whatever he says and never tells his daughters to be respectful. I was raised to respect my elders and was taught how to be a proper lady and I'm trying to teach my son's how to be a proper gentleman and have manners. Knowing the step kids are coming for the weekend my whole week is ruined and I'm basically in a bad mood the entire time! I feel terrible but I tried to love my step children the same as my own but I just cant. When my boys dad and I got together I didn't even know he had kids let alone was still living with his wife even though they were going through a divorce. When I found out we broke up and he somehow sweet talked his way back. Jumping forward to today the 15 yr old step daughter thinks everything's a joke sits with her legs wide open when she's wearing shorts lays in the couch all day (mind you we just have that one couch) blasts her explicit music all day and now has my 5 yr old singing along with her I tell her if she's going to listen to that to please listen to the edited version and she just laughs it off.She also is a cheerleader in school so I'm the one having to take her to the football games practice camps ect. because my fiance tells me too if I say no then he throws a fit and starts to say things like if my kids are such a burden maybe you should leave or if I say I guess then he'll say fine nevermind then tell his daughter Im throwing a fit and I don't want to take her of course I end up taking her anyway.On to the 12 year old...she comes over with her hair looking like she swam in cooking oil and smells of body odor and most of the time with house slippers instead of real shoes and clothes that look like she got off a homeless person so we can't ever go anywhere with these kids. My niece gave her alot of nice expensive clothes and they've been hanging in the same spot when I asked why it hasn't been worn she said she doesn't like them with is another issue with these kids is they're very unappreciative.the 12 year old is also the biggest crybaby I know she cries because we tell her to take a shower cause her hair looks disgusting or when someone changes the channel she wants to watch.And finally the 8 year old...where should I start...she doesn't bathe unless it's here at my house, burps disgustingly loud when we're eating pokes at her behind or front to pick out her underware in public and at home is extremely she has a deep voice has the most annoying cry still talks like a baby and tattle tales on my 5 year old to her dad about any little thing just to see him get in trouble. I was hidden to see how he really acts when it's them two playing and I heard her tell him to pee on the carpet she sat there and laughed at him while he did it and when he finished she yelled out to her dad and said he peed on the floor of course nobody believed me when I said what happened my fiance always says I don't like her and I'm always trying to get her in trouble. Another thing I can't stand is I'm always having to give my plans up or miss family birthday parties and weddings because they're over.I'm so frustrated with everything I could cry i feel like a live in maid when theyre here they walk all over me never clean up after themselves when theyre here my days are spent cooking cleaning up cooking again cleaning up again cooking again cleaning up again im miserable! reason I don't leave my fiance (we've been engaged for 5 years) is because when we would separate he turns into a worthless dad to my boys always making up excuses to why ue cant spend time with them and he doesn't help out financially (he still has to pay me 850 in child support but hasn't payed in almost a year).I'm at my wits end I don't know what else to do when it comes to getting the step kids and fiance on the same page as me...I know I can't possibly be the one overreacting when my brother in law (who is in the same situation with my fiances sister) agrees with me. I'm desperate for any advice I've tried to talk to my fiance and step kids about it and I get if you don't like it then leave knowing I have no place to go or family to turn to that's not an option.
