I don't know if anyone else has been through this but I gave up custody of my son to my ex when he was six and lost all contact with him. It's not something I am proud of and it's a long ugly story. He, his wife, and two kids showed up at my door last week. He is 27 now and turned out amazing despite the childhood he had. He owns his own auto repair business, his father who has passed away was also a decent mechanic. He never owned his own business though. Of course I owed him an explanation of my side of what happened and I sent that e-mail last night which was one of the hardest things I have ever done. He already replied to it and wants some kind of relationship. I know it can't ever be a parent child relationship and he knows that. He only lives 3 hours away.
