I don't care for the article, but the topic itself is worth a discussion.
Obviously there are too many unknowns to truly judge, but unless the baby momma was like 'stay away from my son', there doesn't seem like a lot of reasons not to at least see your legitimate son sometime within in the first few months you learned of him...ESPECIALLY when money isn't an issue.
From what I heard, she didn't try to get money out of him either, she got paternity done on the dude who beat her son to death, thinking it was his, then found out it wasn't and realized it was AP's....so it doesn't feel like she was some awful gold digger either.
I imagine simply spending some sort of time with your child in his current environment would give you at least a gut feeling of his situation.
His reaction is his own, his inaction , however, had some consequences.
