The thing is, your H can keep dragging this on for a long time, she will take every dime and every research input she can get from him... The gravy train's not going to end anytime soon...
That's certainly possible, Allen, but I'm getting the impression all is not well between them. WH's acting confused more than anything. He looks like he's aged 10 years in the last 6 months.
I think he may have told everyone at work that we're done/through/kaput/history, and now he's having 2nd thoughts. If things work out between us as I'm hoping and he tells OW he's NOT leaving me, my guess is she'll throw a temper tantrum, he'll get turned off, and he'll show her the door quick enough.
They're two self-centered, volitale people who can both be all smiles and charm when they want something, and nasty and vindictive when they don't get it. Let's see who wins...
