Hey Kev, With asking your W to a joint lunch, what do you have to lose? If it doesn't work, then you know to take a step back or stay still, so to speak. If asking, I would ask in advance. Then you don't put her on the spot & if she says no, then you can say, ok I'll make other plans then. No big deal.
There's my 2 pents.
