20M

I've been seeing her for two consecutive nights before. She came over both times very late, and left later (busy schedule, doesn't drink). She's a little inexperienced and hasn't had sex in a while, so I took it slow. We tried to have sex the second night, but lots of foreplay, she was too tight for me to fit. We were both exhausted, no lube, so decided to postpone for the next night.

She came over last (third) night and five minutes in said she needed to leave. I teased her a bit, tried to get her naked, she insisted, but kept acting half interested for 30 minutes and finally left. Texting (5 minutes later, she lives close):

H: I forgot we said we'd become fuck buddies tonight
M: You need to be awake for that
H: So I'm not awake enough?
M: Right now? Or before?
H: Now
H: But before I guess
H: Idk
M: I'd have to see to judge. Come back over, Pink Floyd's on
H: No

Besides missing a good response opportunity, did I fuck up anywhere? She'll probably text me throughout the day and try to come over tonight. How do I make sure that's on my terms?
