Hey guys. I hung out with this girl the other day, it went well, we went to a bar, towards the end she got all touchy and we made out, then went home. She made multiple comments about inviting me to hang out in the future and even offered to help me perform a DJ set at a radio station as she knows the owner. When we parted ways we kissed and after texting me she got home safe, that was it. 5 days later I texted her, asked how she was doing and told her about an event I'm interested in, and that we should attend. She told me she was really busy moving to a new apartment but then said the event sounded really interesting and that she totally wants to go.

I then told her that we should go on Sunday and then she went radio silence. That was on Tuesday night and it's now Thursday, no reply.

I'm familiar with being a little persistent when you are in the texting phase before meeting her, but now that we have already met, isn't it a waste of time? I mean she already knows me and despite of showing the opposite in the date, her not responding is a clear sign she is not interested right?
