My feelings is getting constantly hurted by my gf?

what i think is that she is totally taking you for granted o.O i mean its far tooooo many chances. And i dont really know in what kind of relationship you are, but all this would be totally out of question if i was in your place. Make a list of all the bad things she did and how she hurt you and how you cant go on like that and that's it. No more chances, if later, much later she comes back to you, then one laaast laaaaaaaast chance if you really love her and if she screws up again, then Astalavista Baby! It's really to much pain.
