I've been with my boyfriend for nearly 6 months now, and I've really changed. In the first three months, I used to feel really confident and pretty and happy, and believed that he loved me, and so it didn't matter so much if I couldn't see him for a while because it still felt like he loved me. However recently, I've started crying every time we can't see each other (even if it's only for a day), and I think this is because it no longer feels like he loves me when he isn't there. I've lost all my confidence and I don't know what to do. I know the obvious solution is to see more of my friends and not focus my life around my boyfriend, but I don't want to spend time with anyone other than him.
It also doesn't help that recently, he got a part in a play that I really wanted to be in, but couldn't because of other school responsibilities I have. Now I'm afraid he'll be able to see me even less because of rehearsals. I really don't know what to do - I want to be the confident happy person I was at the start of the relationship, but I don't know how to get myself out of the clingy, dependent, pathetic person I've become. Any help would be really appreciated (and sorry for the long post).
