Petite, sorry to hear that.
I am much like KT....man I call dad is not my real dad but married my mom when I was 2 and adopted me complete with his last name. in the fifties it was so much easier to get a kid into school if all the last names matched.
so the man I call dad was always there for me when I really needed him, problem was we were poor and dad worked his azz off to provide for us and was always at work when I was a kid....later when I was a teenager dad was retired due to a bad back and I got much closer to him...and got to see even more of who he was when he was around his first grandson.....sadly he never knew his second one.
he was a caring man and strict but had a wry sense of humor and was as honest as a man could get.
he has been gone over 30 years and I miss him every day.
as for myself, at first I was a horrid dad but like anything else I learned and all I can say is my sons survived and so have I....and my wife still talks to all of us.
