well, lil gal,

Do you ever do anything together on those days or nights that he's over? Like watching movies, baseball games, play cards, or talk? It's possible that your bf is using you simply for sex. It's possible that you are his escape from his stress.

It sounds as though you are unhappy with the way things are going between you two, have you ever tried talking with him about how you feel? What would it take to make you feel better? Him just taking you out every now and then, or are you wanting a larger committment?

Once you are able to decide precisely what you are wanting or needing from him, then you can work on appropriate ways of getting it. (ex: perhaps you want a diamond ring & he can't afford it; or you just need to hear that he loves you every day; etc.) Some wants can't be accomodated. Other wants can be entirely appropriate to expect some accomodation.
