Do I forget I met the guy or give him time and contact him again?

I met this guy online 3 wks ago. We have talked everyday, sexting included. He lives in a different city than me. We agreed to meet each other I would visit him 1st since he has 2 kids. I purchased my travel (hotel and flight) and everything was fine until 2 days before my trip he all of sudden went MIA and I couldn't get a refund so had to take the trip. I was is disappointed but also surprised because I totally didn't see it coming. I texted him that I was totally not mad at all which I'm not I'm more concerned about what happened. I'm sure I was a little naive by going to see someone I just met 3 wks ago but it honestly at the time felt right. The question is now do I just move on and forget I met the guy or do I give him time and try to contact him again?
