Okay so...one sunday I was home alone when my neighbour came to my house looking for my father. I told him that he was not home, and as we were just talking like we normally do, he suddenly asked me if I had any desire to sleep with men. I (in a shocked state) said "not really". Then he continued shamelessly and asked if I would like to try sleeping with him. HE HAS A WIFE AND A SON!!

I immediately rejected him and ran out of the house fearing he may force himself on me. I ran for like 10 minutes until I reached a busy area, and stayed there until it was confirmed that my family was home. I kept trembling and I felt dizzy on my way back. I still haven't told my family about it except for my sister and some friends. What do I do? Should I tell my family and his wife as well?

Edit: After reading all your comments, I have decided to tell my parents about it. Also to those questioning me about running away, what do you expect me to do then? I am a lot smaller than my neighbour so fighting him if something happened was not even an option. I live in a very secluded area, and we have like six families living nearby, and it was a sunday so everyone went to church. I didn't go as I was not feeling well. It was literally just him and me around that area.

Update: So I told my parents about it and they were really upset I didn't tell them earlier. So anyways, they went to confront him and when they asked him about it, it seems he kept saying that he was just joking, and that he didn't mean it seriously, and that he was sorry if he scared me (I know it was not a joke, I still remember how he stood infront of the door and smirked disgustingly while saying it).

My parents told him off for his actions/words and warned him to never come to our house or even approach me if we meet elsewhere, and that they would call the police if he ever did. We didn't want to involve the police since he technically didn't do anything physically so we just called our uncle, who is a policeman to talk to him instead of actually involving the law.

They also told him how they are keeping this from getting bigger just for the sake of his wife and son (his wife asked my parents to forgive him). Also it seems his wife cried a lot and told my mom later that he is very controlling about everything, even about her clothes and makeup, and that she always suspected him of cheating on her but she couldn't do anything or leave him because of their son, and also because she has no source of income if she leaves him.
