Ok, granted I'm a guy, but I THINK I know a bit about women since I've been in several serious relationships. Here's my take. You're about as normal as they come. Every serious gf I've ever has had phases like you are describing. I used to get upset thinking it was me. Like I was not desirable any more/ But I know now that it's the way a woman works. I can't figure it out, but I just accept it. It's normal. You're bf is WAY out of line if you ask me... and so was I when I acted that way. I think maybe some counselling would be a good idea. I'm no woman expert but I think it would help him to understand you better. I hope that none of this came out as offensive cause it wasn't meant to be. Good luck sweetie.
