Dear 4Polar,
I love your tag. One little thought...as self-protection...remember the danger of having our steadiness based on someone else doing what we want. It's not that they don't want to, it's just that they are so hard to train. I'm kidding, of course, but I was just thinking that if you believe you will fall apart if it happens again, I just hate to see you that vulnerable.
Especially since your husband didn't recognize what he was doing before, and it doesn't sound as if he intended hurt. I'm just suggesting you might want to tell yourself, "Hey, I don't want it to happen again, but if it does,I'll be fine. We'll talk about it. He's married to me and he love me and we can talk it through."
Needing it to never happen again is just to scary when you need all the love and support you can get.
Cudos for the big talk.
There ain't no easy way.
