" We can't go on like this. Look at you! It's killing you! And I--I can't do it any longer, not the way we've been doing it till now... I can't share you with something that passes itself off as a marriage, but is really habit and pride and ... empty embraces, or worse. If I loved you less, I might be able to, but--I can't. I won't. "
