Should I drop her?

I moved out west for my first career job out of college 6 months ago. I’ve been really busy because I’ve also been balancing a part time job but I’ve been meeting many people and have made a few friends. I joined bumble bff pretty early on out here and met this one girl. She seems really shy but she’s easy to get along with and we’ve been hanging out every two weeks or once a month or so. I think she told me she had ADHD, but it really doesn’t show so I didn’t know until she told me.
Anyways she takes forever to text back. She recently asked if I wanted to go sightseeing in another town nearby on my off day.
I enthusiastically agreed and now when we’re trying to make plans she’ll say “I can go this day after class” and I’ll say “what about 3pm?” And she’ll take another 3 or so days to answer.
I know she’s busy and she’s told me she is but this is extremely annoying. I have a very demanding job and can send a text especially if planning is involved.
What should I do? Lol
Should I drop her?
