Ok, I may not have answered your exact question. I don't think she would do exactly what you've described, but if she did I would probably be angry at first, but would quickly do whatever I could to be the one at the bar for her every night.
This is pretty much the answer I thought you would give and pretty much the answer that I think most LDH would give. I think most HDW are too hesitant to take this sort of action because it makes them feel too much like the "whore" looking for "just sex" instead of the "madonna" looking for "loving intimate connection". Of course, not taking this kind of action leaves a HDW incredibly vulnerable to the first guy who comes along and does offer any level of "loving intimate connection". Usually other things are lacking in a SSM besides the sex. Every time I go out with a guy who gives me one of the things that my H didn't provide on a regular basis such as pleasant conversation, verbal validation, cheerfully offered minor acts of service, physical affection or hot monkey action I am simultaneously incredibly angry with myself for putting up with such a cr*p situation for so many years and incredibly happy to finally be out of it. I have no clue what your wife's plan is but you probably ought to get busy giving her some of that stuff before somebody else does.
