Am I overreacting?

Ok so here goes... My boyfriend is 47 and I came home to find He had gotten an old pair of my daughters shorts and cut them to be pretty much nothing and He was sleeping in them. I flipped out I mean please help me understand why He thinks it would be ok. And why would he want to wear a pair of booty shorts. The fact the were my daughters is what has Me freaking out completely
