I think I'm starting to understand a small part of how guys operate (in one situation that is)....

When they still email, text, call, instant message you after you've stated your intentions of not dating them, they are possibly thinking there is still chance that you will become interested. They play the part of "friend" until you tell them you have met someone and you have become that someone's girlfriend then you never hear from them again. They no longer ask how your weekend was and no longer try to tell you about their new job, vacation or their brother's new baby.

I suspect it's because they finally believe me when I say I'm not interested or they realize that I am not going to become interested in time and that I am in fact dating other people. I'm not terribly heart broken over it, just find it curious and a little funny.
