like what, weird!?

So I met this guy out last weekend. He’s from another state which is fine. We chatted and hung the entire night while out at the bar, texted and chatted on the phone for the next four days about how he wants me to come and stay and visit him for a weekend. Told me he would rather get to know me over the phone and such and told me to call him the next day so I did and no response and haven’t heard from him since. Should I text him or just let it go!? I just don’t get why guys say things and then disappear
