My bf didn’t get mad that someone smacked my butt. Does he not care?

My (32f) bf (29m) is a super laid back guy. He is very positive, and just an all around happy person. He gives very much golden retriever energy.

He has never given me a reason to doubt us. We’ve been dating a year and he says we are soulmates.

He SAYS doesn’t get jealous. A few weeks ago we were out at a bar and an older man (mid-late 50a) smacked my ass and my bf literally laughed. I got upset with him and so did every other man at the bar. He said “I know you can handle yourself and that guy bought us drinks”. I thought it was super immature and it really embarrassed me. He has since apologized and said he shouldn’t have done something. But I can’t shake the feeling that he doesn’t care about me that much OR that he doesn’t want to be a protector to me. And that is heartbreaking because I do want a protector.

Is this normal?

EDIT: just so everyone knows. When I say protector no. I don’t mean I wanted him to fight anyone. When I say protector I mean mentally and emotionally. I mean I want to feel like I can let my guard down in my surroundings and not feel like I can’t walk around without getting violated.

SECOND EDIT: The brings were bought BEFORE this man touched me.

THIRD EDIT: My bf was not in shock. He was laughing, having a grand ol time.
