I had no clue how to write the title? I know she's more attractive than me, so have no issue with him pointing that out. I'm sure in our marriage I've said someone is handsome, etc.
However, he has recently commented on a meme of her on Facebook. Tagging his friend and saying "if I weren't married... ;)" and I just don't appreciate that. Am I being over sensitive? He 'jokingly' says he'd swap me for her any day of the week and when I don't laugh, claims it's just a joke, etc.
