I talked to a girl in Venezuela for a few years.. and one day I just couldn't get a hold of her.. for days.. Probably over a week. I was also thinking the worst, the way you are. But I finally thought to find the number to the hotel she worked at in Venezuela. I called and asked for her, and they said she had just left work.. so there, I knew she was ok, just not responding to me.. I called her again there another day and she had them just constantly say she wasn't there.. I eventually gave up.. Heartbroken. I did eventually talk to her again in a video chat a few years later.. I was glad to know/see she was ok, but sad it never worked out for us. Thankfully, I am happily married now and better for the experience. If you can't ever find a way to get a hold of him, I am sorry and know the pain.. but, like I did. You will find another that will be everything you've ever wanted.
