I Cant Count On You.

So at the moment it is saturday i just got off work an hour ago its 12:02 AM and my day was alright i guess i was told by my girlfriend that she would either see me Friday morning or Friday night because she had a hair appointment at 11 so i just said either way i just want to see you. So i went to work and she was out with her brother. i didnt think much of it because i was just like eh ill see her eventually before the night is over with. And guess who i didnt see ...MY FUCKING GIRLFRIEND. and its not like im shocked. she does this all the time its surprising if  today at all. She actually follows through with what she says she will do. I noticed her methods that she does, when i want to see her i would text her way before i want to actually see her and just say we should hang or something and she would agree to it. then when i tell her the time i want she would just not text back after i say that or wait an hour and a half and completely change the subject. At first i would make excuses for her but now i am just getting annoyed with it. i love the girl i really do and i put up with her bullshit on the daily. But she is so fucking selfish that its sad. i got to the point of just saying good night to her. and now im about to go to bed because im just getting more annoyed... but on the other hand my night was just fine.
