Why guys cheat on their partner?

Amm... Dislike ppl who cheat on their partners.. Especially married guys and on top of tat got kids.. Do they have DIRT brains or wat.. ??? Why guys are so unreliable??? Do they ever have a sense of responsibility? I WONDER......

Been a nice evening out shopping with alice and caught a movie with cynt... Watch "The ugly truth" with a bunch of real spontaneous movie goes who laugh they lungs out and applauded for some XX scene.. HAHAHA.. A hilarious show.. A must watch to chill out the depressing work life we have...
