Ok, so I have a predicate here. W comes home from work and starts to get ready to go out. I ask nothing about what she is doing, only ask if she's coming home/works tmrw cuz we have to arrange the cars in the driveway.

Thru friends, I remember there is a concert tonight that she wanted to go to. Sure enough, in her calendar. So, my gut feels a bit funny for some reason and I'm learning to trust it. I dig a quick second, and sure enough, guy she had EA with is there at the same show. I have no idea if they went together, as they do share mutual friends. I did say tell the guy a while back that I'd be contacting his wife if he kept up with any shenanigans.

Do I confront her about this? She swore that there is nothing there. And I have been very distant, so I'm not even sure it's my business to ask.

I've been doing really well myself, but this voice inside is starting to panic/get a bit angry about this. That's why I'm here instead of trying to contact her. I am NOT a doormat. If she wants to play these games, do I shut up and deal with it and bleed a slow death and maybe let it work itself out or stand up and fight for what I believe? Again, she's said there is absolutely nothing physical, that they've had a connection cuz they were dating when his brother died. Idk what to think, I don't like looking for things like this, but when I have a hunch, it's usually right. Plz plz plz advice
