First of all, it depends how much of this story is true - but you cannot condemn a man before you have heard his version of events. The critcisim that he has not seen his daughter may well be valid, but on the other hand, the mother could have prevented him from seeing her - in which case, the sympathy should lie with him.
Just as an aside - a friend's husband was being bad mouthed all round our town for being a 'deadbeat' dad to a little girl he'd fathered when he was in his teens on a one night stand.
The truth was, he'd stood by the girl for the first few months of the baby's life, but it wasn't working between them. He then had the baby every weekend and holidays up until the age of 2. The mother by this time had a new boyfriend and wanted him to be seen as the child's dad - so did her absolute best to cut the real father out of the picture. Made it awkward for him to see her, demanded that she didn't call him daddy, said goodness knows what to the child - who suddenly started protesting that she didn't want to spend time with him. It broke his heart when the mother decided that she didn't want him seeing her anymore. He took it to court and got parental rights and visitations - but the mother made it so difficult for him. Would often take the child away when it was his turn to have her - refuse to let her go, and obviously started telling the little girl a few stories because the child used to cry when he did come to collect her. In the end, it just broke him up and he couldn't bear to see his daughter pulled in two directions, so made the decision not to see her anymore - and just hopes and prays that she'll come looking for him when she's older and he can put his side of the story.
Nothing is ever black or white.
