I don’t feel like I’m my own person when I play video games with my bf

I’m always referred to as “(insert my boyfriends name) girlfriend” or when they want to speak to me they directly talk to him “hey is your girl going to do this?” While I’m in the voice chat with everyone.

I feel like shit. No one uses my gamer tag or my name or refers to me as a person. I’m just a belonging. How do I stop this? Or am I overreacting?

It’s a group of 15+ men and one other girl and me, the other girl is cool af and they don’t do that to her. It’s only me. Also, I’m pretty new to the game maybe 6 days playing but I’m good enough as is so that’s not the issue.
