<human>: Can you condense the text into three sentences or less?

Hey, this is actually my first Thread ^^
So to begin with, I am 20 years old (m) and I recently went on a date with that girl and it was pretty good. We went out for drinks and then to our local billiard club and throughout the course of the evening, we had a great conversation.
The next day I suggested hanging out this week and she said that she'd love to meet up. I asked her when she was available and she responded that she is away from wednesday till friday. So I proposed to hang out on Saturday but she declined without rescheduling the date, which she had done before the first date. I said that it was fine and asked when she was free (in the evening). Since then she hasn't answered (monday), which is quite unusual for her (I knew her from 2 years ago, I blew it with her). She mentioned before that she is a little bit forgetful, but I think if you are honestly interested in someone, you wouldn't forget to answer.

I learned a lot recently and I'm trying to improve myself and my social skills (e.g. talking to strangers in the bus). Because I don't have very much experience in dating girls, I feel like she has lost interest although she explicitely said that she would love to meet me again on a second date.

I'm pretty confused right now. I kinda like her, but I'm willing to moving on for good if she doesn't take time or forgets to answer me. I tried to apply the rule of just setting up a date and then get off the phone, however it does not seem to work that well.
<bot>: Should I write a follow up or should I just let her come to me and when she doesn't respond moving on for good?
