So last week I went on a date with a girl I met on tinder and had a good time but didn't close down or make a move, so I tried to set up a second date quite short after (the day after already). There was this concert that she was dying to go to but it was already sold out; I saw that some tickets were for sale again so I asked if she wanted to go but she was quite hesitant and said that she didn't have time anymore because of schoolwork, etc. So I think OK might be coincidence and I try again a couple days later, to meet up in my city (I had visited her city the first date and she would come over to mine the next time) but she said that it didn't really fit her schedule because she was very busy (mind that she said 'for the moment'). A couple of days go by and I text her again, we talk a bit but by coincidence I saw that she unmatched me on Tinder. However, she still replied to my texts and talked pretty much like usual, so it's not that she's ghosting me. I want to know why she would unmatch me, but that would of course be dumb to ask directly. It could be very innocent or she's just not interested, she's giving off very mixed signals so I don't know what I should do now. Next her or do I still have a chance?
