So you go on expecting something will happen and you wait. You wait and wait until you realize nothing is going to happen, so you go to sleep disappointed. This routine of "I'm sorry's" and "I'll work on it's" and "It won't happen again's" just get old. 

The boy cries wolf so many times the whole village begins to just ignore him because they're tired of falling for his constant lies. Until one day a wolf really comes and eats him all up. Moral of the story: If you say you're going to do something, keep your word and act upon it. Otherwise, your girlfriend will be pissed off and you're fucked. Period.  

I'm tired... tired of always sleeping upset, mad, disappointed, etc.

If you're going to tell me you're going to do something just do it. No excuses. If you think you won't be able to do something, tell me otherwise your apologies don't mean shit to me. Sorry.
