Things like that can change though. He may have been just scared, plus they'd already broken up too. It's harder to go to visits when they're broken up. Especially with a new guy on their arm. One of my grandchildren's father was kind of a jerk during the pregnancy. They'd broke up, so it wasn't his baby, went to two appointments, I think (I went to the rest), didn't tell his parents the correct hospital at delivery time, but he made it to delivery, late, but he made it. He didn't participate much, (I cut the chord...), and looked sorta disheveled. The nurses said,
to me, that he wouldn't be around long. They'd "seen his type". After he held the baby, though, total difference. Never missed a support payment (and did that w/o court orders, just did it, on his own), made sure he got to see the baby every other weekend, father's day, etc... any time he could. Started getting his act together, working two jobs, I was impressed. Then he passed away.

I think it's harder when they couple has broken up. They obviously no longer want to be around one another, and then, oops, there's a baby, and here's JW saying the child is his, so, then again, maybe he didn't want to get emotionally invested until the dna test was completed.
