Evolutionary speaking if taken to an extreme women want to ensure parental investment and commitment, whereas men want to spread their genes/ensure paternity. The most typical would be men complaining ”she is only with me because of my money” and the woman complaining about ”he only wants me for my body”. Now, I personally as a woman don’t relate to the latter but if anything am bothered by that I seem to be seen as the ”girlfriend” or ”LTR” type of person. I also know guys who have said ”oh these women only want one thing, I want someone who likes me for who I am”. Now what causes that because a woman fearing being there for her equivalent of male providing and men feared being there for sex or his genes, seems a bit against the typical evolutionary strategies.
