I am so confused by this guy I know. He will always talk to me and smile. If we go somewhere as a group he will usually sit by me. He will remember things I have said weeks before just in passing and will bring it up. If I say I like a certain song it suddenly is stuck in his head all day. If someone said something rude to me and I say something about it to him he will get upset about it and hold it against the person as much as I do. I don't want to read too much into nothing, but I just want to know if there is something there. Any advice?
