If you ask a public forum for advice, don't rake 'em over the coals when they're brutally honest. Personally, I think WhitWhit gave you some good advice (though admittedly you have met guy #2 in person and he lived with you.) If your friends are telling you this is a normal healthy relationship going through a brief rocky spell, I don't think they are really being helpful.
No offense, tweety, but you have LOTS OF DANGER SIGNS here. The guy is "about to be homeless" so you invite him to live with you. He needs to come down to your town but is broke, so you pay for his ticket down. Plus the drama is about chest-high in this whole saga...
And the clincher is that he IM'ed you to break up with you?
Classy.
Perhaps you got a IM meant for another girl he's "in love with." And that's why he freaked and "didn't remember."
I say run too. But sometimes experience is the best teacher. Best of luck.
