So met this girl, cute, catsy, we started flirting for like 3 weeks, and we set up a date for today at 19:00

she tells me she won't make it in time, I said if it's past 20:30 we won't have the date.

she turned it on me in text by saying "If it's not important enough for you to meet me later instead of your errands then perhaps we shouldn't go out after all."

Now, this feels like out of nowhere - she's feeling entitled to my personal time despite knowing me for about 3 weeks

I'm still new to all of this because I'm only 21 and yet to experience many women (she's my 3rd)

Something about this doesn't sit right with me

on the one hand I recognize this as a possible red flag

but on the other i want to go through with her to get more sexual marketplace experience.

what are your opinions? what do you think i should do?

EDIT:

Had a pretty satisfying first date with her Felt her genuine desire for me that night . Though after attempting to set up a second date she tells me she doesn't see it going forward and we should just be friends. Nope. Don't need more friends and not in the mood to be her beta orbiter. Ghosted her since. Once they say "let's just be friends" it's over for good isn't it? Should I keep ghosting her?
