Thinking Too Much

AHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!

I am in a position of being unable to get someone off my mind that shouldn't even be there. He's my former best friend's ex-fiancee, what's my problem? Twice I've seen him in random dreams, last night being the most recent. I keep telling myself no though. I have to at this point because I feel no guidance in this matter. He's a friend, just a friend.
