Jane, I can totally relate to you feelings about that man. I was molested by a dirty old man ages 6-10ish. For years, till I entered treatment at 30, I thought that every old man that looked at me was having the same thoughts. If I saw a man that resembled him, I would have a panic attack. I don't have the same reactions now, but I still cringe if I see a man who reminds me of my abuser. Perhaps your issue will lessen with time, but for now, try to not let it interfere with having a friendship. Realize what your feelings are and where they are coming from.
