Welcome to Bat-shit crazy huh?
IMO this sitch has nothing to do with trusting your H. It was an event from high school…14 years ago! People's memories fade and different people recall events that others don't. I would let your H know that you are sorry for going a little loopy. Unfortunately his actions have brought you here, so he's going to have to understand….this is your new normal for right now.
We have enough to stress about during R, don't beat yourself up over it.
