Please excuse my poor grammar. Public schools in TN failed me.

So, I’ve been dating this guy for three months. I really thought I had finally found my person. He seemed much more interested in building something long lasting than I originally was. We’ve been talking for weeks about him coming to my place for the Holiday weekend. He recently moved 7 hours away for work. Everything seemed ok. He’s been talking for days about how excited he is to see me. I haven’t heard from him going on 13 hours now. I tried calling once but it went to voicemail and he hasn’t returned my call. I’m not sure what I did or what I could have said to make him ghost me like this. It seemingly came out of nowhere and I’m a little heartbroken. He begged and begged me to let my walls down. I finally did and now I’m left on read.
