My S/O and I have been together for 2 years. My daughter is 6 years old and her father is my ex husband who hasn't been part of her life at all. My S/O has 4 kids from Hus ex wife..a 14 year old son and 16,17 and 19 year old daughters. As sad as it is to say, ever since we moved in together a year ago and blend our families, it has been nothing but downhill. S/O has involved his kids in almost all of our relationship issues and arguments to the point where I feel resentment towards the kids. And its apparent that they feel e same about me because they have shown it by their disrespect towards me. I have been accused of being unfair and mistreating his kids..they say I am nicer to my daughter and treat her better than I do them. Which i don't feel to be true, even though I have my issues regarding their behavior towards me, I would never mistreat any child. I am not a monster. But of course,no I don't feel comfortable hanging out with teenage kids who I have seen so quickly form and against me. I have had the most problems with the older girls. I have had to deal withnthe 17year old calling me a bitch and moving out to go live with her mom because she was being disrespectful when she was asked to do something and there was a big argument andi told her that her boyfriend couldn't come over until her dad got home and we talked about the issue. Not to mention that S/O had pulled her into arguments and encouraged her to voice any problems she may have with me. At the current moment, I have left home for almost a week now. My daughter and I are staying at my parents because my S/O and I hadna rather big disagreement because of financial reasons and things got pretty heated..in which his 19 year old daughter walked in the door from hanging out with her friends and upon seeing a few household items that where slammed on the ground in a fit of rage, she involved herself to then point of getting physical with me! I had to force her to the ground and rrstrain her because S/O couldn't control her and the I left with my daughter. I love my S/O more than I could ever explain and I here to say it, but I feel like his kids have ruined our relationship. I don't want to lose him because he has been a great father figure for my daughter who absolutely loves him..but I have dealt with a year of teenage kids who have been nothing but disrespectful towards me and inconsiderate of my daughter. They are always cussing, or talking about inappropriate things around my daughter, and even though they have been asked over and over again, they have been inconsiderate of bedtime and noise levels at night time. All of this especially wit the 19 year old who will come in late on a school night being loud and disruptive. My S/O has been fair in addressing those issues but the girls never change their behavior. They know he isnt going to kick them out or anything because he is the type of parent that says he could never do something like that. Our relationship seemed close to perfection before his kids lived with us, what am I supposed to do now that boundaries that can't be overlooked have been crossed like his daughter getting physical with me?
