relationship help

Elizabeth
So, I'm 17. I've been in a great relationship for almost 4 months now. I've never been treated this great and it's amazing. But for some reason these last two weeks he's been driving me crazy, and I can't stand being around him, but it's for no good reason. This seems to happen with any lover relationship I've been in. Being around him makes me uncomfortable and I don't want him to touch me at all. I don't know what's going on at all, and he's really attached to me.
