Should I tell him I'm pregnant?

I was with this guy and he ended up breaking it off because he said he didn't feel anything and wasn't ready for a relationship, etc. He can't hold down a job or anything. He lives at home with mommy and mommy still supports him and all he does is plays video games and gets drunk with his friends. He did have a job but he quit not long after he started. I know he won't be a good father anyways, and we're not together. And I just found out I'm pregnant. Should I tell him?
