How many men in relationships do you think are actually attracted to their partners? Genuinely.
Or are they with them for convenience and sex and as long as they are not physically put off by them don't really care what they look like.
And I don't mean in a "I love her and am attracted to all of her" way (because I also wonder how real this is and how much of it is a fiction women tell themselves) but in a "I'm not going to get the sort of woman I am attracted to so it's her or nothing" way.
