Husband talking to girl through fortnite

So, i just saw my husbands accpunt through xbox and he has like 3 girls he plays with. That he talks to through mic. I dont know what they say but is it normal for this? Like idk. Hes never talked to girls through games before.

Edit:hes also been distant. We never spend time together./go to bed at different time. We dont even eat meals together anymore.
