Needing advice like ASAP

It’s like we both know our relationship is over, but we just stay together so we won’t be alone. My boyfriend and I’s relationship has really gone down hill the past year. He lies to me a lot, does things behind my back, and he is emotionally abusive. I know, you’re wondering why I won’t just leave him. I’m wondering the same thing. We have good days and we have bad days, mostly bad days. Anything I say to him just puts him in a horrible mood. So now I try to barley say anything to him then he thinks I have an attitude and want to fight with him. His attitude towards everyone else is completely different towards me. He treats everyone better than me. We don’t go out on dates, our sex life is non existent, anytime I I try to have sex with him he tells me he’s too tired, or he doesn’t feel like it, or just no. Something different every time. It’s hard to believe all his excuses because before we got together, he use to sleep with different girls any chance he got. So it makes me feel like shit that he use to have sex with girls all the time and now he doesn’t ever want to have sex with me. He lies to me about the dumbest shit. Talks to girls behind my back. He lives with me, we don’t even sleep in the same bedroom anymore because he can’t sleep with the tv on. I’ve always slept with a tv on the last year we’ve been together and now all the sudden it’s a problem so he sleeps in the other room. I’m about to open a business in my small town at the age of 21 and he tells me he doesn’t believe its going to happen till he sees it, and that it’s getting “handed to me” because my grandparents are helping me get started. He has had 4 different jobs in the last year, he almost got his house almost got foreclosed on, and he got his car repossessed. That was probably the worst time for all of that to happen. It was in the beginning of our relationship and he took all his anger and shit out on me and I still stayed. This guy use to be my best friend. He was so fun to hang out with. He was literally the life of the party, he was always down to do anything and everything and now it’s just hard for him to even look at me anymore. He doesn’t invite me to go out with him and all our friends anymore because he tells me I’m not going to have fun because I don’t like to drink alcohol all time, and because I always look mad and he doesn’t like explaining to people why I look mad. Ok I have a resting bitch face. Like I can’t just smile all the time I would look like a damn creep. I don’t know, he just makes me feel like a piece of shit all the time and I don’t know how it got this way.
