my dad was out of my life from the age of two (i never remembered him) he came back for a week when my gran died, i lived part time with my gran. i got in touch when my son was 5 as i thought it would be nice for his grandad to know about him, his answer was no, just leave things as they are. i decided about 4 years ago to try and find him, i needed closure, i found him through missing persons on facebook, i talked to him on the phone and the first thing he said was he had been trying to find me for years but did not know my married name, i visited him but did not get any answers, he did not want to talk about it.......i said it was okay and that i felt sorry for him, he is in his late 70s and lives alone, has no friends and not much family, i said to him that he has missed out on a brilliant daughter and a fantastic grandson and now a great gradson, he calls every saturday and the only way i will know if something has happened to him is if the phone does not ring one saturday. it has played on my mind for years, i am now 58, but what made me find him was watching my mum get older and thinking i want to speak or see him, not read a death certificate. it will play on your son's mind and probably on the person who fathered him.
