What if he shows up again?

So there was this guy who was asking me out through another person on and off for years. I was kind of put off by him due to his lack of direct communication. He never had a problem interacting with other people, other women, so I never understood why communicating directly with me was such a burden. The final straw for me was when he sent me a Facebook request then acted like I was invisible there. I interpreted as him playing games all the time, able to confidently socialize with others while teasing me, so it got on my nerves.

It really confused and bothered me, especially because I had no clue what his intentions were and I'm also mad at the person who was relaying the information to me. Because I could have been focused on much better things and people.

For some reason, I have a feeling that he could show up somewhere in some way again. He has a tendency to do that, so it wouldn't shock me. I mean I've thought about leaving the area that I live in anyway, not because of him, but because I'm looking into education programs in other places and want more opportunities. Or maybe he's just done with this situation too and won't show up again, I don't know.
