you need to realize something here....regardless of what you think...YOU did not drive your boyfriend away...he's a grown man and made his OWN decision! also, how do you know he's REALLY having a great time just coz he says so? I know a lot of men want you to think that out of pride!
and as for the way you're feeling...it's understandable but...you need to take care of YOU and the rest will follow! be gentle with yourself but firm at the same time. i.e. you NEED to at least eat something, a car can't run on empty and neither can you!
take gentle care ok....and sorry i'm not a great advice-giver but know i do care.
