Ladies what would you have done ?

Let’s start by saying if I have grammar errors don’t mind me have a newborn and a 2 1/2 year old lol. So I was an idiot and trusted a guy... we got together and shortly after I found out we were expecting. Things had already started changing like freakin out if I got home a little late from work then I must be cheating kinda thing. Mind you I worked sales representative for AT&T. You can’t just say hey I know I close in 20 minutes so I can’t sell you a phone because I can’t be late getting home... well then his drinking got out of hand where he literally got so drunk he drove almost to the house stopped to take a piss and passed out in his car (car still running door wide open). That night I told him grow the fuck up and act your age. He’s 41 with an 18 and 14 year old boys. It’s wasn’t but about a week or two that he decided one night to pack up everything of his and leave... he then asked for my forgiveness and I told him till he figured his shit out he wasn’t welcome back. I was updating him on how the pregnancy was going and then he comes back with wanting a dna test I told him whatever you can have one after she was born.. now his family is telling me I’m at fault... that I’m keeping him from his daughter (she is 2 weeks old now) I did wait a week to tell him (and I gave her my last name he didn’t help provide anything but stress while I carried our beautiful daughter) as I am trying to figure out how to care for now both of my girls with out help as the father to my oldest isn’t around (long different story) when I told him all he could say was yes I heard. She’s adorable... like I’m honestly confused how it’s my fault I’m sorry that I feel i should get a as little stress free birth and a week to myself to figure this out. But if he heard prior to me telling him why didn’t he reach out? why didn’t he ask how she is doing if she’s healthy all that?... his family claims he wouldn’t walk out on his child but he did...

These are just a few mind you two weeks before this my dad had just passed away.
