Pregnant and dad doesn't want to know

Can you give us some more information about your situation please?

So who cares what he wants, you tell him, when child is born you file for custody and child support,

Take him to court (for child support and custody), he will know about your child then and he can explain himself in front of the judge.

Take him to court, more information is needed but let the judge sort out the fact the father doesn't want to know
