You're trusting that stated expectations are the same as actual revealed expectations, which is something I doubt in this area. If I'm right, men doing more of what women say they want will not lead to more relationship success for those men.

I agree that it's hard to judge the reasonableness of other people's decisions, but I think that if they either fail to find what they are looking for (i.e. I expect a luxury car for the price of an econo-box, and am persistently disappointed), or expect more than they offer (i.e. I expect a partner who is equal or superior to me in all respects), the expectation may be unreasonable.
