What do men really want ?

Ok so here like the life long question , What the hell do men really want ??? After encountering multiple events and hearing zillions of stories , I can't seem to figure out a secific answer. For example my friend Billy is married to this tall gorgous Russian chic. Shes quite younger than he is, newly graduated college, and seems like she has an amazing personality. But he complains about her everyday, cause she graduated a couple of months ago, she doesn't work, hasn't even tried to fix her resume, and sleeps all day. He gives her everything she wants. And example # 2, this woman I know is super hardworking..does double shifts @ work.. provides everything for the household, cooks , cleans just everything. I don't understand... men cheat on both the hard working or the lazy. So what the hell do they really want, lets just say getting together w/ anyone is a fucking lottery.
