My ex and I were together for a month and he started calling me names and treating me like I was nothing calling me stupid for this and that when he wasn’t even in my life at that time,

I ended up getting pregnant with his kid haven’t been with anyone else but him in a long time, he didn’t react the way I thought he would he just rubbed it off like he didn’t care making jokes like “baby you can be a milf now” and I’m super torn like he was just talking shit and treating me bad but I tell him I’m pregnant with our child and he thinks everything’s fixed?

Trying to call me baby and shit and eventually when I was actually trying to talk this out and figure out what we’re gonna do he says “anywhoooooo, Imma go to bed. You contemplate what you wanna do with it. Have fun.. or whatever” like really? Maybe I’m just being dramatic but him being like that makes me just wanna do this on my own. After our relationship ended a couple girls came to me saying that he had r@ped them which I’ve been SA so I believe them, he doesn’t have a job, and honestly is kind of a loser if we’re being honest I feel bad because now I feel like my baby won’t have a father and it’s gonna be harder…I don’t know what to do

UPDATE: he said he wouldn’t be there for the child unless I was with him I told him no and that I can’t put myself or my child through that and he left
