Did I handle it well

It's gonna be a long story, I'm trying to improve my interactions in person and online, this one was random and spontaneous.
So thursday I needed to take a test for COVID and while I was there, an old highschool crush of mine that rejected me in the past, recognized me and approached me.
We talk for a bit about our symptoms..
Then the interaction went like this:
Her: Well at least now you have a free week (you have a free week without leaving your home if you do a COVID test in my country)
Me: I wish, no days off for me. You went to college right?
Her: Yeah, in ##
Me: wow so fancy
Her: I know I'm a fancy girl now Ahah
I'm studying (some bussiness shit)
Me: ohh I thought you were gonna be (her name) the lawyer in a cute outfit
Her: nah but I study law tho. oh that actually would be fun, I would get a call from you, for me to take you out of jail
Before I could respond they call my name to do the test so I said "It was good running it you take care bye" small hug and move on
Yesterday I got a text from her: Hey, how are you feeling
Me: I'm built different, the only negative in the house. You?
Her: Positive :(
Me: But you are feeling okay?
Her: Yes, "3 lines talking about COVID tests she did"
Me: Thats good, at least you have a free week not sure if you deserve it tho
Her: Ahahah of course I do I have 2 exams next week
Me: The old (her name) that I knew would do it without study
Her: Its harder now unfortunately Ahah
Me: we survive Mr. ### Class, 2 exams sounds easy
Her: ahah true you are right
the problem is that I have 2 this week and more 2 in the following week
Me: maybe you deserve a free week after all ahah
Her: Oh I know I do Ahah
Me: Well good luck future lawyer
Her: Lawyer? Ahah
Me: Am I wrong?
Her: yes ahahah
Me: What's the plan then
Her: (some Business shit that)
Me: Good luck in your 47 exams, future business lady
Her: Ahahah thank you so much

For some reason, now that I have improve my social skills and I'm in shape l feel like a owe my old self to try something with this girl. She rejected me in the past tho, like 4 years ago
Should I hit her up after the exams weeks?
