Have an hb8 tinder match, got her number and texted her on Tuesday, texted her and set a coffee date for today. After she engaged a convo and we chatted, nothing flirtatious but build rapport and she was pretty interested. Later that night I asked her if she worked out asked me she said it was her rest day and tomorrow (Wednesday) she's doing back and bis and asked if I had work tomorrow (wed). I told her "good excuse for being lazy lol. I work everyday, why?" She didn't respond at all and finally today she sent me a text saying she couldn't make it tonight because she has a group project and no one did any work, and for me to text if I'm around her area(college campus) because we'll hang.
I haven't responded yet but should I play the same no reply game back that she did to me or say "alright, I'll let you know" or is there a better response?
