If your gf (official long relationshiop) says she's gonna call and she always was doing something else or she just forgot... what would you take from that?
Maybe she's just don't want shit with you? I mean... long ass relationship... that's not how you end it........

forget about it.. it's just a phone call. perhaps, though, she doesn't look forward to calling you because your relationship isn't so good.

You shouldn't do long distance relationships. That's my advice.

So you mean that... if you wont see your girl from all your life for a period of time, you shpould kill the relationship?

Oh sorry, I mis-read your post, I was very tired. Thought you were doing a "long distance relationship"

Okay if a girl is not making effort to contact you, you're losing attraction. Ideally your girl should be contacting you, like, just to say hi, and want to hang out tonight, etc.

Have a think about how the relationship is going in general, post here if you want.

If her life is really busy at the moment because of work or studies or anything else that may cause her stress, I'd let it slide because I doubt it has anything to do with you, and more to do with how her mind is preoccupied with other things.

However if that's not the case it's as has already been said: she's losing attraction to you. You could make an effort to increase it again (there's plenty of tips around here but some tips in a nutshell: be ambitious, be honest, do the things you love, tell her how much you love her (if you don't love her just end it), know that you can live without her and she may respect you more for it etc.) But then if you don't like her that much it's time to end it and move on because there's no future coming of the relationship.
