Help?!

Is it my bf or is it me? Im on BC and been on it for a year and a half. Lately, I explode for something little he does. I only see him at night now, and it's been a while since we've gone out. Everytime he says he's gonna come hang out or take me out. Some sang friend has to pop up and he goes with them. Am i over reacting, is it just some moody side effect, or is he doing something wrong?
