It's been a shitty weekend. After a nearly week long hiatus and super shitty behavior on his part, I just swallowed some pride and initiated a hang out. response I get?

"Maybe Later?" and when I asked for clarity: " I'll let you know in a couple of hours, but don't wait around for me"

Of course, the sad, dull girl part of me— despite being hurt and pissed—wants to wait around.

Not gonna do that though. But I don't know how to respond in a way that doesnt sound...catty and immature. I don't want to sound all go with the flow, cool girl, it doesnt bother me either. I

potential response so far: 'Ah. : / Well, if you're not really available, another time then.'
