I was guessing she's not a lawyer, honey -- I was being sarcastic to let you know that this person knows nothing about LAW and her situation (if true) cannot help YOU in your situation.
I know this bothers you greatly and I suggest counseling. It is very difficult to grow up without a dad and I'm sure you are angry, confused, and hurt. I can assure you without even knowing you that it is NOT YOUR FAULT. You are an innocent who got caught in the crossfire of failed adult relationships and bad decisions. Counseling could really, really help you. I hope you pursue YOU instead of old, bad junk in your past. Take care of YOU - get counseling; let the old stuff go - counseling can help there, too.
