I also think that may be over exposure. You may need to think through the lasting permutations of the different avenues of exposure.
For example, in my case, I REALLY wanted to expose to the OW's husband. But then my mother warned me that since the OW was his student, he could end up losing his job. I knew I'd need his income, with or without him at home, so I let that idea go.
So think about the ramifications, like, for example, would both of you be mega uncomfortable every time you went to a school function. Because, know that info like that spreads around schools like wildfire.
