He left when dc was a few weeks. He’s highly successful, well known in his field and if dc was ever to look him up in future there would be loads of information about him online, his achievements etc. I worry this will really affect dc as it’s an insight into his dad where his dad simultaneously couldn’t be bothered with him. His dad has no other kids and unlikely to as he’s almost 50 now. No idea if he has a new relationship. I really wanted them to know each other but having reached out a few times the last year, it’s obvious he couldn’t care less as he’s been totally silent. I can’t believe anyone can do that to their child, it tears me apart. How can I make this better?
