Should I let him leave and just focus on me and the baby or try to make things work ?

Yall this some crazy shit my entire pregnancy was crazy because or the father family was giving me hella sh*t about dna and so when I had the baby got the testing done and like I already knew the dam baby’s his so fast forward we’ve been dating for a couple months it’s been hell one minutes he’s telling me he wants to be a family and then the next it’s me finding out that he has a picture of some girls nudes in his phone, I found out today that he’s back in contact with his ex on all social medias after he told me he blocked her I had a really big surgery a couple weeks ago so he’s been staying here to help me with our son since I couldn’t lift him or anything I could barely walk and was in so much pain he told me he would stay until I get back in my feet back to being about to pick our son back up and bend and all that but we get in a arguement and he says that I’m trapping him here and all this stuff. He’s been hiding from me that he’s back in contact with the ex since he’s been here everything’s been 10x harder our sons not on the schedule anymore or anything I tell him that I don’t want to argue in front of my family and he still does and I tell him to stop and he doesn’t he doesn’t have a job right now and even when he did he still wasn’t giving me shit but like 40 dollars a dam month I’m scared to leave him because I do wanna have my lil family but is it even worth it anymore should I just continue with college and focus on em and the baby and just let him leave and go back home to his city with his mom ? Yall im lost I need some advice 😩
