If you schedule a date with a girl and she cancels, should I just ignore her and let her reach out to make plans or do you try again? For context here's a little basic story:

Cold approached this girl, had a funny convo, got her number. She goes to a college only minutea away from mine, and around our colleges theres tons of bars and restaurants and stuff to do.Texted a bit the next day, told her I'm gonna be at school all day and to let me know if she feels like getting drinks at this fun bar. She said she'll think about it, I made some little jokes, then she says yea she wants to meet. 2 days later, I text her about 2 hours before the time we agreed asking her to confirm. She says she can't cause she has a class at that time and proceeds to send me her schedule so I don't think she's lying. I'm like ok you should have told me you had a class lol next time then and she's like yea sorry I compeletly forgot. I didn't reply. Should I reach out to her in a couple days with new plans or just wait for her to?
