Okay so I need advice

So my sisters work friend tried to set me up with her nephew we made plans to go on a date after he got back from work cuz he was going to Mexico for a vacation with his family.

Well the night came but we ended up not going out cuz it got really late so we decided to go on a date when he gets back from his vacation. I told him have a nice vacation and I'll see him when he gets back.

Well we didn't talk the whole two week vacation which I didn't mind cuz he was with family. But it's been three days since the day we were suppose to hang out and I still haven't heard from him.

What should I do?
