Re: boyfriend leaving....
Odds are he's trying to get in a whole lot of partying in before he heads off to boot camp and enters a whole different type of world. That being said, it's lousy that he's treating you with way. I agree with the previous poster - in boot camp, they are allowed to make short calls and write letters - an ex of mine was in the Marines and that's how we survived. I'd try talking to him again; otherwise, you'll know for sure how he feels once he's gone - once there he's either going to miss you like crazy and contact you as much as possible or the distance between you both will continue. At least then you'll have a definitive answer.
Hang in there and hope you get some answers soon.
