Curious about what other TRP followers would do...

Date last night. We met at a nice restaurant. Our conversation was good; solid kino and rapport. She paid for dinner. We were gonna bounce to a nearby bar, but realized it didn't open for another hour, so we walked to a park. Obviously the next step was to bring her back to my place -- I had already planted that idea.

Suddenly, she got a call from her brother. Apparently he is moving into a new house but his car broke down in a bad area. She became upset and she teared up. When she hung up, I asked her what happened. She told me. She had to go, so we hugged. She apologized and claimed that we would definitely meet for a second date.

She hasn't contacted me since. Unsure if I should ask about her brother, or thank her for dinner, or just wait? She's like a 6 and I'm dating other women, so I don't care if we never reconnect tbh. Thoughts?
