My boyfriend is emasculated in my eyes.

We went his company Christmas party last night. As we were waiting for our Uber out on the sidewalk I noticed a girl standing by herself waiting for her ride on the corner. I didn’t like that she was waiting by herself so I was keeping an eye on her while we were outside talking. This drunk kid was roaming around talking to himself, and eventually I saw him go up to her. I was watching the whole time to see her body language and see if she was okay, and when I saw her walk away I walked over there and my boyfriend followed. I just stayed in her general vicinity and she walked over and asked if she could wait with us, and I said of course I came over here because I didn’t like that you were waiting by yourself and that the drunk guy was bothering you. She was super appreciative and we waited with her until her Uber came. As her Uber got there the drunk guy walks straight up to it and opens the passenger seat and is trying to get in. I walk over there and let the Uber driver know this guy is not with her and don’t let him in the car. I tell the drunk guy to go away, this isn’t his Uber, and try to shove him off the car, but he isn’t budging. I look over, and my boyfriend is still standing on the corner looking at his phone to see when our Uber is coming. I call out to him to come help and he still stands there. Fed up, I go back inside the venue to find some guy bartenders who instantly drop their clean up to come outside and help. My boyfriend just stood there the entire time and watched ME fend off a drunk guy by myself. His defense is “he doesn’t know what people are capable of and people can be dangerous”, but he’s perfectly okay with watching his girlfriend walk into that. I really don’t know where to go from here, but I can’t even see him as a man anymore if he’s not going to protect me.
