Should I call it quits after my girlfriend of 1 year and 6 months stood me up?

Alright my birthday was Thursday my girlfriend, she called me up the night before and told me happy b day and then text me bright and early Thursday morning "happy b day" then later that afternoon when she got off work she took me out. Well the night was going good until I got home, I was feeling a little frisky (wanting sex) well she told me no. So did I just then started to watch TV, well she continued asking what's wrong and I said "nothing is wrong" well after that she just kept on asking so I said "every time I want sex you always say no (we have dated for over 1 year and 6 months, we used to date back in high school and now back together 4 years later). Well she was then like well I got to go home and do my homework...I said "you had all day to do your homework but now you really need to do it once we start talking about sex, this always happens", well she storms out of my house and I follow. I tell her sorry her feelings are hurt but its true, anytime we have an argument she run's away instead of facing the problem. For about 15min of talking I assumed we both calmed down and she went home. Well Friday night I text her saying I knew of this place I wanted to take her and that it was fun. Well she texted back saying, tell me what it is, I'm excited, I want to go can't wait. So I text her that I will pick her up around 3 p.m. Well 3p.m came and I called her up to tell her that I was coming, no answer and reply so I waited, and waited and called her again 1hr later and still no answer, so I waited another hour and called and waited still no answer. Well 9 p.m. came along and I sent her a message saying "So you stood me up, I can understand if something very important occurred or you wasn't able to come out, but at the same time you still knew we had plans tonight and could have sent me a text or answered my phone calls. When we got back together you apologized for the way you acted towards me, now look at the way your treating me, standing me up. Thanks for letting me down". I do care about this girl, but I think I'm wasting my time and deserve better, should I pull the plug on this girl and tell her or just not talk to her anymore.
