Why do I feel like I’m being unfaithful?

So I’ve been playing PUBG at night recently. I don’t normally make friends on there, but I got put in a team with 3 guys and myself. They’re good at playing and we ended up playing 3 games together and one of them added me. We became acquaintances, cuz I don’t feel we’re friends yet. But we’ve been playing a few battles together and talking a little bit. Like he knows I’m married, and tiny things like where I’m from and age. But that’s it, and I know his age and name and where he’s from but that’s it. There’s absolutely nothing romantic or anything going on, and he hasn’t hinted at anything or anything. We’re just friends in the game. I know my husband is very jealous so I haven’t mentioned the guy at all. But I feel like I’m being unfaithful. I know there’s absolutely nothing wrong with making friends and having friends. But I still feel like I’m doing something wrong. Is that normal?
