It's insulting to me, I feel, because what I do/have to him is disgusting. I don't see how that's not insulting (the way he said it, not that he thinks it). I really am not being snarky in asking this, but please explain to me better how there is a disconnect between the two? If I was on that page and he didn't know me, it would be disgusting to him. I don't get it. He doesn't have to be interested in them like we are, but after having those things for 2 years and he suddenly tells me they're disgusting is at the very least disconcerting. All he had to say is, "I'm not interested" or "I don't find it as amusing as you do." Instead, he used a blanket statement that included me.
OK this is gross but it's sort of like baby poop , poop is gross but we get over it and change our children's diapers.
My husband's nose was badly broken many years ago. I don't care I love him and think he's very handsome but if you showed me pictures of only noses I would never have picked his nose and an attractive nose. Your feet are a small detail of the total person he cares for, photos of random people' feet are objects he has no attachment to. Yes it's likely if he did;t know you and saw only your feet he might say "eww", without you your feet are not a person and unless he has a foot fetish feet/shoes are probally pretty low on his list of priorities , you could probably have a corn/wart wonky toe and he wouldn't care. I also believe it's likely if you dissected him there would be some feature on it's own that you would not select but it's really is a case of the whole is greater then the total of the parts.
That doesn't mean I don't understand why your hurt/insulted say it exactly like you did here " My feelings are hurt . I have tan lines and wear those shoes , when you said tan lines are disgusting I am hearing you think my feet are disgusting"
