Having Lou Gherigs disease doesn't make her protected by the law from exlax attacks, lol. What is she going to do, atrophy at you?
EDIT: But yeah, I hate it when couples cheat on each other. I don't see the point, why are you in a relationship when you can't commit yourself to the other person. If you want to be in a relationship with someone else, break up or get a divorce. Better yet, don't get married so hastily...one of my friends got engaged to a guy after 2 months of dating him...we all know where that's going >_>
