I think my mom honestly hates me..

Hi. I’m 14 years old. This might get a little long but I don’t have anyone to talk to. I’m sorry.. I seriously think my mom hates me. Like actually. Her and I used to be close. My dad and her divorced (my dad was sentenced life in prison about 6-7 months later). My dad and I were inseparable so it took a pretty big toll on me. She had a boyfriend and got pretty serious with him. I didn’t really like him, but his daughter and I became like best friends so I tolerated him and basically told my mom I approved of their relationship. My mom got pregnant with my brother who is now a year and a half. I love him so much. But, when she was about 6 months pregnant her and her boyfriend split. It took her a while to “get back out there” and I wanted her to be happy so I encouraged it so much. She met this guy (I’ll call him A) and apparently she knew A from when she was younger. It was more of, A knew my mom but my mom didn’t know of A back then. I guess they had the same friend group. So they talked for a while then stopped, then started talking again. I encouraged it, I wanted her happy. But, one thing she promised me was she would be with a Christian (sorry if you don’t believe in God) and it really upset my family that he doesn’t believe. She also said she would take it slow. And she lied. Literally I met his 4 kids about a month later. My mom has 3 kids. So altogether that’s 7. She never wanted that many. We moved in to a new house and he tries to parent my little sister who is 10. He wasn’t trying to parent me up until recently. And, I am all for respecting adults. But, I don’t respect him. I talk back on purpose. I don’t care. I told him he means nothing to me. I literally hate him. He talks to my mom like she is a child. If she interrupts him, he gets mad and yells at her and tells her not to like she’s a kid or something. They’re also not clean people. Today, I was telling my mom how this house is gross. He got mad saying I should get up and do something then. But I do. I did the catbox today and swept the bathroom. Usually I sweep the kitchen and my sister helps me with loading + unloading the dishwasher. He wouldn’t stop going on and on. He always has to be right in arguments so I told him to shut up. Over and over til he actually did. Then he went in my room and literally said “grab your stuff I’m taking it out” Bc apparently since I’m so disrespectful I need to learn respect and I’m only going to have a mattress that’s mine in the room. Thankfully, my mom stood up for that one. But he took all my stuff off my dresser and threw it on the floor. (I’ll put pictures) and he took out my tv that my dad bought for me. I just feel like my mom hates me. I told her how I think I got a 4.0 this semester (it’s my first year of high school) and all she said was “oh. That’s cool.” She just doesn’t care. She thinks I’m going to get pregnant too. I’ve had a boyfriend for over 2 years and I admit I have had sex. But, he doesn’t pressure me and we are always safe. We use condoms and have it only before my period because i know I’m not ovulating then or close to it. I wanted to tell my mom when I first started having it so she could put me on birth control but I can’t talk to her about anything without her telling A. I get so upset and I envy all my friends because they have tight bonds with their moms. I wish I had that. I can’t even tell her I miss my dad because she gets mad. I just need someone to talk to. I want to join counseling or therapy but I don’t know how.
