What would you do in my situation?

So i had a baby with a guy i was with casually. It ended briefly bc he got carted off to jail and then to another state. I think it was a dui.

When i was with him he just smoke, drank ans drove w/o a license.

All of that turned me off ...

Now. I dont really have a way to contact him. No phone number, email, all he has is an abandoned Facebook..

I have no real way to reach him ans now im so nervous bc i feel like ill be opening up a can of worms...

My baby will be 1 at the end of the month.

What should I do?
