She has no idea...

She has no idea that she is about to lose to me, I am tired of having plans with her and then it takes her 4 hours after the fact to apologize and cancel. A part of me wants to just tell her to go back her ex who didnt treat her right, maybe then she will realize what she had. The part that sucks is that when we are together its like the only thing that matters in this world is her and i. I dont want it to end.................
