Help, I don't understand what's going on with my boyfriend?

That's odd that he would do that...does anyone else have access to the folder?? My first thought was that he's hiding it from another girl maybe, or else he deleted it so that he wouldn't be tempted to look in it. Whatever the reason, he is distancing himself from you. He is slowly trying to drift away and end the relationship. As for him agreeing to the visit, maybe he said yes at the time, but who knows if he was serious. When you bring it up again, try to set a date...if he's flaky and indecisive, then he's not serious and you shouldn't waste your time or money on the trip. It's clear to me that you want to be with him, but he's not sure about you. In my experience, it's pretty hard to fix a relationship when you live so far apart. Maybe you should reconsider trying to hold this together.
