past come back to haunt me :/

about 7 years ago, freshman year of college, a boy sexuality assulted me. I wanted to kiss him but he demanded more, a bj. I refused but he talked me into it. you know how it goes. you keep it to yourself, forget about it, and move on. only now i just found out that he is the head of the local adult soccer league and my husband is super involved in that. they've gotten friendly. I haven't told my husband because I didn't know they knew each other until today. and thankfully he's apparently acting like he doesn't know me. I looked and they are friends on Facebook and instagram so I know he knows who I am. idk. I don't want to say anything or make a big deal out of it. DH has talked about him but hes got a very common name and i knew him in college. didnt think it was the same person. I'm just a little unnerved. today I finally got a chance to go watch DH play soccer and I saw him there. it was just weird. I guess I just wanted to tell someone. I want him to keep playing, he's got friends there, but I don't want him to be friends w that guy. any advise?
