Yep, shunning.....that I did...only wanted to be around people that didn't make me feel guilty about what I was doing.
She doesn't know what you are doing. You guys aren't talking. So, her guilty sneaky mind is thinking you are being sneaky.
Calm is good. Can you show other emotion and remain calm? If so, I'd do it. The last thing you want right now is to blow up and do something you don't want to do. You want her to know that what you are doing/have done is because you love her and want to be with her and want to save your marriage. That is impossible if there is a 3rd party. So, showing emotion to back that up would be a good thing I think. Don't expect reciprocation. I know you got the Love Dare. In it, there are things you will do that show love but aren't sit down conversations professing that love so that should be good.
