I need help...

I just had my baby in October. Baby’s dad (boyfriend) is an alcoholic and gets super violent when he gets drunk. He has anger issues and gets mad over the littlest things ever. He turned the shower on and my dad went to use the restroom and turned off the water because he just saw it running so my boyfriend got so upset that he didn’t even want to talk to me and my dad even went to say sorry that he didn’t know and he still gave him an attitude response. Boyfriend doesn’t pay for rent. All he pays for is our king size bed and a refrigerator. The bed was his idea because he said my queen bed was too small for the 3 of us. I told him you can’t be getting mad that he turned it off. He pays for the bills and he saw it running so obviously hes going to turn it off if he sees no one there. And then a few weeks ago I found messages with him and a family friend talking about being unfinished business and that maybe if it’s the right time they’ll get back together. This family friend knows about me and my daughter. She even showed up to my babyshower with her babydaddy now ex ( reason why she’s texting my boyfriend) I know I can’t put all the blame on her because she was the curious one and knew my boyfriend was on his 4 beer but it was also his fault for giving her entertainment while me and my daughter slept right next to him. They deleted the messages. Well we went to this brewery and he got super drunk and tried to drive off with me and the baby ( i was breastfeeding her in the backseat ) I was able to get out quickly while he was back out and he drove off leaving us there. He eventually came back to get us and I told him I’m not getting in if you’re going to drive. I told him turn the car off and give me the keys and get out and then I’ll put the baby in. Well driving home he was yelling at me so many names and that I’m a stupid bitch and I’m the reason for his actions etc. He put hands on me when I took him to his moms because I was not going to be putting up with that( . I have pictures ) he promised me he was going to stop drinking and so far he has. However he does not put the time in to be with his daughter after coming home from work. All he does is play video games. I gave him the baby so he can sleep her and all he did was continue playing video games while she screams super loud and doesn’t bother to do anything. I went and got her from him and told him he needs to leave to his moms and that it is over. I don’t want him anymore. It’s points to have you here if you aren’t going to help and just play video games the moment you get home from work. You can’t even wash your own dishes from work. All you do is throw them in the sink in hopes I wash them like a slave of yours. So go back to your moms. HE HAD THE AUDACITY TO TELL ME NO ! I don’t know what to do guys ... I need help. I can’t be with a guy like this anymore. It’s mentally draining and affecting me. I breastfeed so she’s acting up because of the frustration that I have from him. He’s no help. He doesn’t even pay anything ( other than the 2 appliances ) I pay for food and buy her everything. I asked if he can buy her diapers and he said you have money don’t you? And he claims he supports us ... BOYYY WHERE?!!

He has even said I’m take you to court and I’m get half or more time with my baby .. blah blah blah

His mom is a person who I feel like isn’t a good person to leave my baby with per say. She has told me that when her kids were little she couldn’t stand them so she would leave them crying there for hours. Last time we went to visit her, she held my baby for less than 5 minutes and said I’m tired already here I held her for like an hour already. LADY WHERE ?! and lately she has been complaining that we never take her the baby and that she wants to bond with her and wants to be there when she cries so she can run to her and pick her up etc. But I honesty don’t feel like I trust my baby around her. She is an odd lady. I legit get the feeling that she would do something to my baby because she can’t calm her down when she cries.
