I don’t want a new family

This always stresses me out. My mom has a boyfriend, and he moved in with us this year. I can’t stand him. It’s not just from some selfish adolescent point of view, its because he’s always on my back about something, for saying the wrong thing, for not being a different person, for not wanting to go to church with them.. He likes to make me feel bad. I’m naturally indecisive, like if someone asks me a question I dont usually give a flat out answer, i say “i dont know” because Im comftorable with it, and he makes fun of me because of it. He’s always preaching to me about how he was when he was a kid and how he wished he had listened to everything anyone ever told him, but I cant get it through his dumb head that Im NOT him and I might just be a little more mature than he was at my age, because his mother practically spoiled and smothered him. He thinks i should have everything done for me, but that makes me feel very dependant and I dont like that. I usually prefer doing things for myself. My mom asks why I’m so defensive when I talk to them, and thats bcuz he always is criticizing me, and trying to get to me, and my mom, who is usually a strong idependant woman, becomes a sniffling little creature when he’s around and wont speak her mind anymore. And that makes me sick. I dont know why she has to change in his presence. He’s not worth that. noone is.. It ticks me off too when he starts talking about my dad. He thinks that just because my dad used to be an alcoholic, that I will be too. I’m more mature than most of the high schoolers. I’ve never touched alcohol, because when my dad was drinking I used to listen to him and my mom fight constantly, then he got remarried and him and my stepmom would fight constantly , in front of all of us, (me and my 4 brothers) But she was strong, and stood up to him, and i respect her. shes like a 2nd mom to me. After a number of years, they were divorced and my dad stopped drinking and married again, and gave me a new little brother named steven. my moms boyfriend insists that I’m going to hell. I have issues with church. I dont get it. It seems they want $$. And I have issues with the whole religion thing. And my moms boyfriend thinks Im some kind of demon child. Maybe I am
