I went on a date with a girl I met on POF. It went really well, she said she wanted to do it again, and we kissed. I asked at the time when we could do something again, and she said potentially Sunday but she'd have to get back to me for valid reasons.

We had a lot of fun and continued chatting via text, and last night I asked about Sunday again. She said she couldnt do it and explained why, to which I responded with 'Want make plans for next week then? No worries if not obviously' and I've literally had no reply. I sent another message today saying 'Take that as a no then heh, have a good weekend. For the record just say next time :)' and one after asking for the reason. I know she's seen them, so I'm just very confused. I'd be fine with a reason telling me no, but the curiosity is killing me.

What do I do?
