How do you co parent with someone who doesn’t want to be involved?

I’m 21 junior at university I’m graduating soon possibly going to law school but I got pregnant by a guy and he wants no parts of my child’s life. It sucks because I’m a broke college student and he already graduated years ago finished medical school etc he’s very much stable has a Mercedes Benz , own apartment and good paying job legally I can get a lot of child support bc of his income but I want a parent for my child not a check, how can I efficiently co parent with him?
