I need advice..

My child's father and I just broke up after 2 years he just now admitted he cheated on me constantly while I was pregnant as well as before and after and had my son around her as well.. anyway he's 20 , he doesn't have a job , not in school , no car not even a permit, lives at home, nothing going or trying to benefit himself he has bipolar and schizophrenia (I didn't know about the schizophrenia until way later on when I was pregnant.) He intentionally got me pregnant by not pulling out when he said he would and said he was gonna trap me (admitted this when I was 8 months pregnant and yes my birth control i was on failed)

He constantly screamed at me and called me names and was emotionally abusive but said it was always me I couldn't say anything.

So.. my son was being watched by him during the week so I could work and graduate high school, his mother told me he hands him to her and leaves most of the time, my son has such severe diaper rash and was covered in pee and I washed him changed him and put clean clothes , it was ridiculous , if he doesn't get his way he smashes things, and breaks things, threatens people, throws things, and I heard my son crying in the back.

Now I admit I haven't always been perfect and yes I've yelled in front of my son (I'm human) but never smashed things or didn't change him or left him to go out and cheat or whatever etc..

So the police got involved because he smashed things and got his head cut open and I didn't think he was stable and I wanted my son back with me ...

Everybody says I should take him for custody and child support.. and he's not stable and my son shouldn't be around him for now unless he sees him for a few hours with someone because of his anger and no job and not trying etc.

Should I take him for custody and support? If he doesn't pay child support I know he'll go to jail and that's a worry.
