text: why is he acting like this? me and my ex-boyfriend were really good friends for about 2 years before we started dating. i would say we were best friends.  we were attracted to one another but we were both afraid that a relationship was going to ruin our friendship. however we eventually got together. it was good at first but after a while our situations changed and we felt that it was best that we go beack to being friends so we could both concentrate on ourselves. we were still cool for a long period after that, then he started acting funny. he would try to make me jealous sometimes by mentioning other girls or doing things like that. then for some reason we just stoppped talking. now that we have a few classes together we see each other practically everyday. when classes first started we would talk and text each other and things went back to normal. now he will look dead at me sometimes and wont say anything. then he'll call out of the blue and want to talk for hours. i'm confused. why is he doing this? relationships are complicated...period.   instead of investing your time and mental energy trying to figure him out, i would take time to focus on the things that make you happy or things that deserve more attention.
