Hello - my 10 dd has not had contact with her bio dad since she was 6 or 7 yrs old. And before that it was here and there. He to has a drug problem, finance problm, girlfriend problem, etc.. married my current husband when she was 9 and i wish I would have married him when she was alot younger and the bonding was more natural. Dont get me wrong he is a good step father, great example - he even tattoed her name on his arm next to his sons names, but she is older and understands the relationship - she gets shy about calling him dad, but wants to, etc.. I do feel sad for her sometimes because i know she craves that male bonding, she will ask about her bio dad, etc..I grew up without a father and wonder and miss what it would have been like as well, but what is worse than that is the memories I have when I was 10 when i visited him (which was rare) - he could be mean. so I think it would hurt your daughter more to have contact and when she is older she can make that choice. Anyway what I do with my daughter is all I can do, apologize for my mistakes, make sure she knows she is sooooo loved, and I am honest about her biodad and his issues. We also changed her last name to our new family last name which is alot easier and cheaper than adoption. She was very excited!!
