Input: My wife is still friends with an ex-boyfriend of hers and whenever I bring up that I'm not very comfortable with it, she says I'm being jealous and possessive. For Christmas, this ex bought her bras and gave it to her in person, with a sny remark about knowing her size. I complained there and then and said he had no right, but they said I was being loud and it wasn't a big deal but friendly "banter". Later on when he left, my wife called me rude and said I didn't trust her. AITA for not trusting in my partner and not wanting her to be friends with somebody she's known before we ever met?
