No, I know. I'm open to suggestions! Ok let's put WAHs behaviour this way: Normal in the lead up to my leaving Europe. Normal seeming communication during the 3 months apart. Comes back, bomb, goes to friends place for 3-4 weeks. Finally has 4 days alone-time and decides "I'm leaving you".
He coulda been nasty had I been there, but doubt it. He's not even *nasty* now.
