Asked a girl out on a date. She replied with some story of how she'll be a little hungover from some party the night before and she'll have to see. Whatever. Instead of just walking away I slipped back into my beta ways and said "I'll talk to you tomorrow about it" and walked away.

Should I bring it up tomorrow when I see her or just learn from my mistake and move on?

Edit: thanks for the advice! I'm just going to forget it, learn from my mistake and move on.
