AIO – for thinking my boyfriend is jealous of my DAD?

My (F18) boyfriend (M20) is jealous of my dad and it’s making me rethink everything

My dad raised me alone and we’ve always been close. He filled both parenting roles, so we’re naturally affectionate and calling him “daddy” (he’s the only one I’ve ever called that). It’s never been weird to me.

My boyfriend met him a few months ago and immediately started acting off. He said it was “wrong” for me to wear a bikini around my dad at the BEACH. He gives me weird looks when I call him “daddy,” and last night he literally left after seeing me cuddle next to my dad on the couch while we were watching a movie. I was just latching on to his side and he had one arm around me.

Lately I’ve started holding back with my dad just to avoid upsetting him and that’s not okay. There’s nothing inappropriate about our bond. But the way my boyfriend keeps sexualising it? That’s what’s gross. And honestly, I’m starting to rethink this relationship. Am I overreacting ???
