I'd want more information before I decided whether or not this club's expectation is even reasonable. What exactly is the burden on the wife to be out of the house?
What does an evening meeting actually mean? Is it from, say, 7 o'clock to 9 o'clock? Or is it 7 o'clock until 11 or 12 o'clock? One is treating myself to dinner out and maybe browsing the mall, the other is having to amuse myself until after my bedtime when the only things still open are the 24 hour grocery stores and gas stations, bars, and the late night fast food joints.
What is the weather like? Where I am, we're smack in the middle of the coldest, snowiest winter in eons. Once the sun goes down, the temps drop below 0 Farenheit and it's miserably cold. The roads are bad. Visibility is poor at night because everything looks gray or grayish-white in the dark because of the snow drifts and the snow on the road and often it's been snowing as well. I would not be pleased with anyone who thought I needed to be out in that because No Girl Cooties Allowed.
Are there comfortable and enjoyable options for the wife if she leaves the house? Are there places that she can go and enjoy herself, or is this community in the middle of nowhere and unless she wants to hang out at the gas station, she has to drive an hour?
And not least, is leaving her own home to indulge an exclusionary men's club against the wife's own philosophies and moral code?
