Life's just hard and I need to vent 😓

To start I found out my boyfriend had cheated on me sometime between August and September but I didn't get told until December 23rd, two days before Christmas and I was 32 weeks pregnant. I chose to stay for the sake of our daughter but I've lost so many feelings for him. It's a constant argument, anyway fast forward to now. I am currently 4 weeks pp, and we've argued non stop. He tells me things like hoe he doesn't care if I cry and doesn't care how I feel, he screams at me in front of our daughter, calls me a bitch tells me I'm heartless etc. I just feel so helpless, I have no friends because no one wants to be friends with someone with a baby and now the guy I've been with for 5 years is treating me like the dirt on the ground. I had an emergency c section so getting around is so much harder then before, plus I can't drive yet due to just having a baby. I'm used to taking care of myself and doing things on my own so depending on my boyfriend, especially now is making it harder on me. No one ever tells you how having a baby effects your relationship, but it's hard. Any advice on how to help get through this...
