>>210737Seems like a lot of advice from virgins. Find a way to "find out," without having snuck through her stuff, before confronting her.
You probably do need to get it out in the open, though. If she is just bored and fucking around it might be less of a problem than if she is completely done with you.
I would be at rage level 11 if I found out the way you did. That's way worse than if my wife just told me.
