I just found out that the OW's legal first name is the same as mine.
OMG, your real name is "Slut?" I don't blame you for being upset. If I were you, I'd get it changed right away. What were your parents thinking???
Seriously, Shoe, don't give it any brain space. Like Fig said, someday you'll feel sorry that OW got stuck with your X. I know it doesn't seem that way now, but it will happen.
