My story.. (abusive bf)

So I started dating a guy I met on tinder (crazy right??) anyway, we started partying and drinking and one night at his uncles birthday party while we were sitting together by the pool he asked me to be his girlfriend. Of course i was already head over heels and said yes. 3 months after dating him (knew him for 4 months in total) , I found out I was pregnant. Wow. I was 18, he was 22. Our relationship was amazing, with some bumps along the road as any other relationship. We would go out to dinner, go visit family, go on big trips, beaches, everything. He would buy me anything I wanted. But he has a bad side of him nobody would see, and he’s such an outgoing fun person, people wouldn’t even believe how bad of a person he could turn into. First of all, in the beginning of the relationship like within the first month he cheated on me and had sex with 3 different girls without me knowing. I later found out because he told me. He would always tell me if he did something wrong, but ever since that day he hasn’t had sex with anyone but me. After that, he has gone on tinder and looked for girls and even went on a couple of dates while i was working my evening/night shifts.. it still hurts me even though that was a while ago. He’s also an alcoholic, and a sex addict.. anyway, fast forward to now. Our daughter is 3 months old. I love her so much and am a stay at home mom since he’s a teacher and makes enough so that I won’t have to work for now. Anyway, this past weekend he started acting differen. He hasn’t had sex with me in over a week and just jacks off while in the bathroom to NOTHING. no porn nothing.. I know he hasn’t cheated on me or has been texting anyone because I literally have everything. He has physically and verbally abused me the past two days. He’s done it plenty of times before but now I feel like I’m over it.. I’m over being treated the way he treats me. Don’t get me wrong he buys me anything and everything I want. But he doesn’t understand that materialistic things don’t bring me happiness.. my daughter brings me happiness, him being nice to me and making me laugh makes me happy. Not a nice pair of new shoes or a watch. That doesn’t change the fact that he sometimes verbally and physically abuses me. He says that since I’m not working and won’t be able to pay rent or feed out baby if he leaves that the court will just side with him since he’s a teacher and gets over 40k salary. That didn’t stop me from telling him that he needs to pack his things and go. I’m not going to put up with being abused. I will do what I can for my daughter and love her endlessly. Idk.. I’m just so hurt and feel so weak. I have such anger deep down in my chest when he hurts me. I just want him gone out of my life and to pretend that me and my daughter don’t exist
