I have met dads like that, and yes, sometimes I wonder that too. Leaving the financial aspect of it aside for a bit, I think there are different categories:
1. Men who never really think about fatherhood. The child for them is just a part of the woman’s body, not theirs. It’s generally a “woman thing” and their role ends at having sex with the mother. I assume this has to do with their background, perhaps the way they were brought up. I have an uncle like that. Luckily he never became a father.
2. Men who generally realise that they are fathers, but don’t know how to cope with it. They just don’t want to take on that role, probably because they think they’ll be bad at it and also have other priorities in life (like finding a new girlfriend or buying a car). I’d say this is the majority of fathers. They don’t realise the importance of children unless they actually get to meet their own kids, and even though they’d probably make good fathers given the chance, they never discover that. These are the people that have been our fathers and grandfathers for centuries, and are now alienated from their offspring for the simple reason that the divorce rate is higher nowadays.
(from what I understand Lynne’s ex is in this category)
3. More modern dads who’d like to play an active role in their child’s life, but are not allowed to do so by the mother (including court orders etc). This is becoming quite common unfortunately. The reaction is that the dad eventually gives up because he can’t cope. Studies have shown that they have a much higher chance of going into depression or committing suicide as a result, and the only solution is to pretend their children don’t exist (which partly explains the refusal to pay child support).
4. Dads who keep fighting for their kids forever, usually against a mother with different views on parenting. Eventually one or both give up and kids get two sets of families, which is wonderful actually.
5. And then you get guys like me…lol
I have a divorced friend who has a son around my daughter’s age. He is not my godson, but he was going to be, and I think of him as my godson. I have often taken him to play with my daughter, babysat for him and so on. I’ve spent a lot more time with him than his own dad. Actually the mother is so busy that the child grows up with the grandmother, who’d be more than willing to let the father take him. Whenever I ask him why he never goes to visit his son his excuse is that “it’s too far” (7km…that’s less than 5 miles). When I offer to give him a lift or take him next time I go to pick up his son, he’s always busy or the time doesn’t suit him. He complains that his ex-mother-in-law doesn’t bring the child to him at his own home, and that he always has to find a way to go there. So yeah, I don’t get it sometimes either.
