Actually, what he means is that "you're the best customer representative he's ever had to deal with."
Sorry about that, I just had to get it out.
Anyway, actually, i'm sure he's a great guy and the sex was amazing, but he sounds like a very typical Type-P male to me.
Type-P stands for (Practical). This guy gets through to a business call, takes care of business, then.. he gets you talking to him.. gets you to meet him on a couple of dates, has amazing sex and then leaves. (Practical).
Did "he" need to care about feelings? NO!!!
Here is what "you" did wrong. You did not let him know how you felt. And I don't mean sexually. We all know you let him know well enough that kissing and sex where on your mind. So he naturally thought, great!!! (Sex with no strings attached).
Had you let him know about your intentions or deeper feelings about him, then.. if he did what he did, he would be a Type-J.
Type-J stands for (Jerk).
However, had me not left off. He would be a Type-H or Type-B. In short, husband or boyfriend material. What I would do, is try to get in touch with him nicely.
Do not fall under the impression that he left you. For all he knows, all you wanted from him was sex. Try to talk to him in a friendly way, and ask him how's it going?
Try to SLOWLY get back into contact with him. If you rush and spurt out your feelings, you WILL SCARE HIM AWAY, even if he's a nice guy.
Hope it all works out well..
P.S. Don't mix business with Pleasure.
