How would you talk about it?

10 years ago I had a close friends at my church. I'd come over and play video games and go swimming. We were all very close like family, our dads were even really close and we would go on fishing trips and spend weekends together.

Anyways when I was 13 I went away for the summer with my family on vacation to get away (I was mugged at knife point so my parents let me stay with family out of our small town for awhile to deal with it and get away).

When I came back I went to my friends house like usual to go swimming and hang out. Their dad was recently divorced and suddenly everything seemed off. Anytime I would go to the kitchen or bathroom and was alone he was there and would hug me everytime and say how much he missed me over the summer and how well I've grown. When it was time for me to go home and the dad was gonna drive me home as soon as we left the house to get in the car he grabbed my ass and told me he still couldn't believe how sexy I'd gotten.

I was freaked, this was a close family friend and I considered his kids like my cousins and him an uncle. I stopped going to their house, church, and when he came to our house I stayed in my room and I never saw my friends again. Never thought it was ever anything to tell me dad or anyone so I never did not even my husband.

10 years later my dad is still close with him and I've avoided the guy all this time. Now I'm living in my dads rental and my dad keeps asking to let his friend come by because we have aloe vera and cactus in the yard and he wants to cut some. I keep saying no but I really don't know what to do. He doesn't understand and I really don't want to tell him because it's been 10 years and at this point I don't think I'd be believed and I even question myself if I over reacted to the situation. I've never talked about this before so if anyone has advice I'd really appreciate it.
