BOYS

Are all boys so immature??

My ex-boyfriend is acting like I've fallen off the face of the earth. I mean I know THAT'S normal, but we ended on seemingly good terms. It just kind of fell apart and things were just to the point where we were waiting for the other person to end it- which I ended up doing.
I'm not expecting us to be best friends and stop and have chats in the halls when we pass but looking the other way and completely ignoring me all together is a little bit rude- especially on the good terms of our break up.

I'm just completely flustered and embarassed that I ever even dated this jerk in the first place.
I'm a human being not a disease. He's friendly with his other ex-girlfriend who he dated before me. He actually talks to her sometimes- but he won't even look at me in the halls? He's just a jerk.
A JERK.
HOW MANY OF YOU HAVE DATED A GUY/CHICK LIKE THIS????
