Oh yes, it will most certainly tick her off. But, will she be so determined if her secret affair is brought to the light?
If she is contacting him there is nothing you can do but wait on her to see that you are the better choice, or see that OM is not what she thought and life without you and her family is not one she wants to have. While you are waiting, you make yourself the best person you can be. This is so hard.
Her freedom is one thing, having another relationship is another. YOu can give her "freedom" in many ways while still married.
I think back to my time when I was in this early stage of the affair. If I thought I would be exposed, I think I would have stopped everything. I would have been pissed, but I would have stopped. Sometimes I wish my H would have known sooner so that I wouldn't have gone as far and have wasted as much time. I don't know.....so many things to decide....
