IME, quickly surveying the broken marriages I know of, it's the women who wear make-up and spend most of their life in the gym or looking for the next high fashion item whose DH's leave them.
Their DH's just look for the next model who doesn't have to try so hard (and will dump her in 5-10 years too when she needs to up the make-up and gym routine, start looking at botox, etc).
Having said that, I def look better with make-up than without, although I am aware there was a time in my life when I didn't need it at all and a time later when a quick slick of vaseline on my lips and eyelashes was enough
