abused by my dad

About 9 years ago my father molested me. It started off that I got up and went to his bed one morning, like usual. Except my brothers weren't awake yet. He got up and shut the door and locked it and then laid down and a little while later he asked me to rub his stomach, then he kept pushing my hand further down and made me jack him off for awhile, he said "don't tell your mom I let you touch that" and then he finally quit, except he started to touch me and rub on me, when he asked how it felt, I told him to stop and he did. I then went to my room and cried and was so upset. I never told anyone but my best friend at the time (still my best friend today)and my fiancé.  I dont remember telling her but I had a break down a few days ago and I told her I had to tell her something, I was so upset and she told me that she remembers the entire conversation and we talked about it. 

I am now dealing with this and it is causing severe depression, I want nothing to do with him and I don't want him to walk me down the aisle in December. I don't know how to move past this or get over it...
