やったー！離婚しました！！

Wow, she looks really happy! When Kumazawa bookstore put this on their building, I wonder if they knew what it says.

I also like the "heart" on the book cover. Is this is real book, or some kind of joke?!?!?

If you are divorced, you don't want to say "I divorced." You should say "I am divorced." You could expand it and say "I divorced my ex-husband in 1993 because he was cheating on me." We can say ex- for a person who is no longer with you. Another example is "I broke up with my ex-girlfriend the other day." You can respond with: "Oh, sorry to hear that."

"Cheating" is when your lover goes with someone else while you are still together! (Not cool.)

I haven't met anyone that has said anything like "HOORAY! やったー！ I am divorced! 離婚しました！！" Have you?
