I'm with this guy for over 1 year. He treats me very differently compared to his friends. Generally, I'm not totally happy because he treats more like a tool than a friend. He only treats me well when he needs me to do stuff; right before, during, and right after. He stopped telling stuff about him soon after he got a huge loan from me and said that I'm annoying. He says "no" to me as often as he says "yes" to his friends with the same request/offer at the same time. He returned the birthday gift I gave him last year giving me a lame excuse. I questioned myself a lot, is it me?
