At this point (sadly) Luv's H has no desire or intention of working on himself, ending his A's OR working on the marriage.
CG - you make some good points about why she shouldn't bother. He really has done some nasty things.
I guess I push toward hope rather than away, unless Luv says that she doesn't love him at all. But she does. That doesn't mean the R is healthy, nor will be.
So I push for hope. If/when a D is final, then I figure never look back in regret - enjoy the good and move on. Until then...try the things that haven't been tried.
Pursuit only matters when there is a risk of chasing them off. I think there is no risk anymore for her...
