Guys, how would you feel if you abandoned your biological child?

So you had sex/hookup or been having a fling with a girl your not serious about and don’t consider a wife or find attractive enough

She gets pregnant from that hookup or fling. You tell her at the start you won’t be involved and she should get an abortion. She doesn’t

She gives birth and you stuck to your words. You’ve never met this child. The child is 4 years old and you have 0 interest in the child. You’ve never even met the child.

So do you just move on with your life as normal? Like pretend nothing has happened and your not a father or do you genuinely feel bad inside?
