My stepdaughter is 18 years old and moody as hell. Her behavior has gotten better but I’ve noticed that a lot of times she treats my 2 year old daughter like crap only when her dad isn’t around. Sometimes I try and think it’s because she doenst like me. As she admitted this to her dad. Her and I have come along way and I feel like she’s doing a little better. But today she has really upset me and I didnt know how to deal with the situation so I just removed my daughter from her sight. My 2 year old was excited to go in her room but my stepdaughter stopped her right before she was about to enter and said no because he had slime. Then she sounded annoyed and told her “lexi go with Cindy” oh yeah, she doenst tell my daughter to go to “HER MOM” she says my name instead. Now my daughter sometimes calls me Cindy. My husband sometimes says something but most times he lets her slide with it. I have stopped saying anything as she doenst get the point. Anyway, she did not let my daughter go in her room so when I went to check what was the problem she was hiding behind the door as she had just got out of the shower and she told me, lexi could come in after she was done changing although she had her clothes on. She thought I hadn’t seen her. She was lying, she just didn’t want my 2 year old in there. She’s done this a few times. I just don’t understand what’s her deal, she’s 18 not 15. How do I deal with this BULLSHIT?

I forgot to mention. She locks herself in her room if it’s just me home. If her dad is home, her door remains open she even comes out to the living room most of the time. She’s mean to our daughter unless her dad is here. This is why I’m frustrated. I get that she wanted privacy but if we’re home just the two of us, even after I’ve asked if she wants to come out to watch a movie or I’m making some food for us to eat, SHE WILL NOT COME OUT.
