I am very sorry to read about the sexual abuse you experienced at the hands of your father. It is a very grievous thing and I am proud of you for confronting him and forgiving him. I wonder how things have worked out between the two of you since and how your relationship with your other family members is going.
Bodyguard's advice to seek therapy is good. I prefer the 12 step approach myself. I am looking for an alanon meeting in my area. Although there was no alcohol issues in my family, my father's sexual assault and his long term sexual addiction qualify me into an alanon room. I hope to find a sponsor with whom to work the 12 steps of recovery. Best of all, it's free, and I hope to make good friendships and aquintances. I will also go to s-anon, (survivors of those with sexual addictions,) but those rooms are usually full of the wives of sex addicts. It is a little more difficult to work the 12 step program there.
I hope the best for you. It isn't easy, but with the right support I think we'll make it just fine.
