Was supposed to meet this chick I've already been sex with a few months yesterday but rather than go smoothly as usual she went and pulled some annoying crap.

She didn't even message until I asked her what her ass was doing when the time came up. Said she's with her family. Right. Then I say what happened to our supposed time, she says to give her time and she'll be out soon. Except this goes on for two hours.(I'm already disengaged giving one word replied and hitting up one of the other girls on my snap).

Finally she wants to apparently meet at like 10pm and I'm too tired by that point (gym, finals etc.) so I say no. She then gets upset saying sorry she had family Easter dinner to attend to and she misses me and sends me a selfie. The behavior annoys me and I just ignore. Except now she offers to meet today again and is double texting for me to answer. Don't know how to react, should I accept or just ignore her more days? Feel like she won't take me as seriously if I just immediately accept and she'll get comfortable flaking. Or maybe I'm just overreacting and missing out on sex.
