Basically i have not seen my Real dad for the best part of 19 years, 
We used to be real close and spent loads of time toghether. However my parents split and after a year of me visiting at weekends and holidays it stopped, and since that day i have not known his location or even if he was alive or dead . about 5 years ago i was contacted by another member of that side of the family and i regained contact with my Grandma and aunties etc. However they also had lost contact with my dad due to a family argument!!.
Well the dilema is i have after some digging found his current address and telephone number. 
So what do i do?? 
baring in mind the last time i saw him i was 11! write a letter, turn up on the doorstep,phone him or just let it go?? I really dont know what to do for the best.
Any ideas??
