You have every rights to be angry, normally I would come in saying nice stuff like try to understand him and all, but I have to go with you on that one. Before Alex I had some bout with some guys which ended up pretty much similar to what you had with this dude. As decent dude that we are we always going to question ourselves first, trying to find where we got wrong, but sometimes it's just not us, and I believe that the dude should have think twice before playing with someone's feeling like he did. If he wasn't ready he should have just voiced it out and I am sure you would have understand and went slow. But no too many dudes or dudettes have no fucking idea of what they want. They meet someone who knows where he's going and want and they get scared or confuse. Well off with their heads, feelings are not to be played with period.
The dude that I had before Alex is now trying to befriend us because he now see what he missed but I don't need those people around me, and neither do you. Let him soak in his confusing soup, once he had swallow enough of that juice he should work on growing some balls and stop being scared.
