Should I call back?

I have been friends with someone for a few months, and there has always been an attraction. We started hanging out a couple of weeks ago, and had a first “date” a few days ago.

Anyway, I didn’t hear from him the day after but had a missed call but I didn’t call back because I didn’t notice until it was late. I acknowledged it with a message. Didn’t get a reply to that, but have come home to find another missed call.

Should I call back, or leave some mystery on Friday night and call tomorrow?
