I was still reading 窮鼠はチーズの夢を見る (The Cornered Mouse Dreams of Cheese) by 水城 せとな (Mizushiro Setona) and on the page 29 I stumbled across a word which I keep forgetting and keep looking up in the dictionaries.

恭ちゃん...あのね ... 別れてほしいの。  -- Kyou-chan... well... I want to separate.

Seeing that she is married to that Kyou-chan I guess we could assume that she wants a divorce.

• 別れ --わかれ-- (n) parting; separation; farewell; (lateral) branch; fork; offshoot; division; section;

• 夫婦別れ --ふうふわかれ-- (n,vs) divorce; separation.

This is a compound of 夫婦(spouses) + 別れ(separation) .
夫婦 --ふうふ(P); めおと; みょうと-- (n) married couple; spouses; husband and wife; couple; pair

• And then at wiki the divorce is listed as 離婚 --りこん-- (n,vs) divorce.  I guess, this is a legal term, then.
