He was away for 6 months or so. She was there too as an au pair. I think it wasn't just her. It was a group of them all messing around. Sure he may pine for her. Who knows? There are so many other women he knows since then and before who I would think would be more appealing to him. She seemed a bit rough and vulgar for him. Certainly aggressive. He tends to go for / flirt with gentler more intellectual and creative types (see...should he really have a type after being married to me all this time??)This is quite strange. Yet before you married he had an active life with Aussie? Maybe he pines for her?
