Men acting like I don’t exist when other men are present

Just wondering if this only happens to me or.....?

So the other day my boyfriend and I walked past our new male neighbor and I said hey to him, he looked right past me and said hey man to my boyfriend.

And the other day I was walking out of my apartment complex, with another guy a bit ahead of me, and there was this delivery guy looking hella confused in the parking lot. He turns to the guy and says hey do you know where blah blah is and the guy says idk I don’t even live here and goes to his car. Then the delivery guy looks at me but quickly turns away before I could open my mouth to help him and keeps trying to look for the door he was looking for. Like ok...? I could understand if he thought I was with the guy and didn’t live there either, but it was clear we were not walking together.

And another time me and my boyfriend were in the grocery store and the male greeter guy looked past me and said have a nice day to my boyfriend.

I have a lot more examples but don’t want to type them all out. Does this happen to anyone else?
