Should I be worried?? :(

Bf has cheated in the past but hasn't recently (for years) We have our moments but overall everything is good. My problem is he plays Xbox and talks to friends he meets and I recently found out there's a girl on there too that he talks to. Im by him when he's playing but not always. Anyways I wasn't even weird about this until i heard this bitch straight up trying to make conversation with him (other guys are talking on there too) so I'm likeee uhhh wait a min. Am I crazy or would any of you be weird too if you were in my shoes? I'm just more worried about not being around and something transpiring. I know I should trust my bf but it's so hard to trust this for some reason..

Btw I mean talking on a mic while playing his game
