Today, I found out that my brother is engaged to marry an ex-girlfriend of mine. This comes almost two months after my brother divorced ANOTHER ex-girlfriend of mine. FML
This is the OP (just signed up, so I could comment). For those who say "who cares and why do you?", take a moment to see the big picture. That big picture contains two words: family reunions! Who in the world would want to see their ex-girlfriends at family reunions? Especially, since their new role in your life is that of a sister-in-law? I'd love to let bygones be bygones, but it's hard to do when they become your in-laws!
