im not sure how you can get anyone to suggest what you should and shouldnt do with only knowing 2 lines???
How old is he?
What caused him to go off the rails?
Are you any what to blame?
Do you need to change before you expect him to change?
I didnt see my dad from about 1 till 16 / 17, due to moving around (been in 20+ houses in 26 years), i've seen / been in contact with him abit more in the last 5 / 6 years. i dont blame him assuch but maybe he ould have done more, i blame my mum as i belive the only thing that she had to hurt him was me and this is why i didnt get to see him.
