Am I overreacting? Dumped girl for rescheduling date

I've gone on several dates with this girl over the span of 2 months and she has made it a habit to switch plans or reschedule with poor excuses.

Here’s how it went down:

she sent a text apologizing and told me her family reminded her she had plans for dinner on Saturday. Other times it was forgetting to write down plans with her sister, unexpected plans with friend, etc.

• I told her not to worry about it and that we can reschedule for another evening this week. • she said she's tired for any plans this week let's plan for next week. • I said I'm not available. • she suggested the following week. • I declined. • she then said that she's too stressed to even ask for my reasoning. • I broke up with her.
