My parents got divorced 3 yrs ago but my dad just moved out 3 months ago. My mother got a boyfriend and my dad left. I was with my mom mon. To thurs. Then shit hit the fan and I told my mom that I hate her boyfriend. I pretended to like him to make her happy. I lived with my dad and he took full custody but it's not legalized yet. He hates my mom but I still love her. Tonight I went to her house to spend the week there. She told me there'd be no boyfriend so I stayed. 2 hours after she said that he showed up. My mom told me she would get him to leave but I guess he told her no because after 15 mins she tried convincing me to let him stay. After 15 min of arguing I called my dad to come get me, which hurt because all week I tried convincing him that she changed (guess she didn't ). When I left my mom was in a terrible state crying and whatnot now I feel terrible.
