Bf has gotten into cross dressing

He has a whole skirt and crop top outfit he wants to wear when I peg him.... first of all I don’t even like PEGGING. He has a choker necklace that has a heart on it. He wears g strings now. He’s gotten really feminine and I’m just not widdit... is it time to break up. It’s been 5 years and I love this man been together since highschool. He’s my first. Just never would’ve expected this to come out. And he says this is what he’s fantasized about for YEARS
