This is more of an old situation bothering me again and it feels like my significant other (we're not married yet) just could care less about it still and possibly thinks it's my fault primarily. I really just want to vent out loud as a way to get it off my chest so here goes. When I first moved in with him, he had a daughter living with him who at the time was about to turn 17. I remember being excited thinking we were going to get along great because she was old enough that I assumed there wouldn't be any problems. I was dead wrong, and after a few months of me being here she pretty much hated me and still to this day hates me. Long story short all three of his adult kids don't have the best manners or attitude due to being raised poorly by the mother who kept them away from their dad for half their lives. While his daughter lived with us we constantly argued over our kids because she would constantly do things that I consider rude, selfish and disrespectful. She only ever wanted her dad's attention when she wanted him to buy her things but would also never want to go out with us. She was extremely jealous of me and only ever spent time with me on a couple of occasions. She would constantly try to get alone time with her dad by wanting him to join her in her room privately to talk. Every time we went out to grocery shop or do something together, she had the option to come with us or babysit my son who at the time was still in diapers; she would always rather stay home in her room. I feel like a bad person for even thinking it a possibility but it really felt like she had the hots for daddy and was trying to be his sugar baby.

     Long story short (again) she was self-centered, lazy, and her dad I feel just didn't discipline her enough but we'd always argue when I brought the subject up. She wouldn't help out around the house until a week of asking nicely then getting her internet taken away for not listening. I've heard her on several occasions while she was here talking bad about her dad to people online and acting like a cyberbully. One day we all got into an argument and her dad left the house saying we needed to sort our differences which ended up in her slamming the doors calling me names and moving out, leaving a closet full of garbage for us to clean up. She admitted before walking off calling me names that she thinks I'm the reason her and her dad stopped having a good relationship, and I responded to her comments by saying she acts like an ungrateful child. I said nothing else because I didn't want to deal with more attitude. Well since she moved out I've kept an eye one some of her social media to find out she has been telling everyone that she was abused and forced to do everything around the house and babysit my son all the time and thinks I'm this and that how much she hates me blah blah blah. She has even told people how her dead step father (who she wasn't even close with I might add) was more of a father to her than her real one.

     So back to now, I do feel things could have been handled differently when she was living here, and I will also admit that my son hasn't been the easiest to handle around here since I moved in, but he is Autistic and she had no excuse other than jealousy and a crappy mother for acting the way she has. It still bothers me to this day because I have had past experiences with abusive people and struggle from Anxiety, Depression and possibly PTSD from my son's biological dad and I am always feeling like I don't belong because of what happened with her when she was here. Recently, she messaged her father on Facebook, with a simple "I love you" and they talked back and forth for a while just enough for her to ask if he still holds a grudge for what happened, he ignored the message and replied to the other part about where she's been and whatnot. This bothers me because it feels like he would rather have her in his life than me and my son, and doesn't care about what happened between us. Now I do understand a parent will always love their kid(s) and wants the best for them, but I don't feel like he be talking to her like nothing happened. I'm upset that he hasn't bothered confronting her about it when she even messaged him before recent times about the situation saying she didn't appreciate how he lied to her and let me his (gold digging gf) take over and push her out.

     Thanks to those who read this whole thing, I really just wanted to vent about this situation in the hopes someone who has been through a similar situation knows they're not the only ones. It is really frustrating dealing with someone who has a bad attitude and feelings towards you. I grew up with a jealous older brother who had to move in with a cousin for abusing me and still to this day proves to be a "problem child" (he's in his 30s) who is addicted to alcohol and drugs, has a huge ego and my parents still have him in their lives and refuse to listen to me when it comes to the "he needs tough love, kick him out" talks because they're scared of his temper.
