To back up a bit... Boundaries are about you, ken. About what YOU will tolerate, what YOU do. Not about what others do. Pack her bags! She may call your bluff, so what. What do you really have to lose? Your wife? She's already out of the marriage by having an affair.
Fear is a message telling you that you may not be prepared for what's coming. It is just a message. Rather than take that message and turn it into paralyzing worry, take concrete steps to become prepared.
Avermont recently did a fear exercise. She wrote the most awful things that could possibly happen. When re-read, you can see them in perspective. (Her were quite entertaining, sorry aver! it was funny!)
So, what is the most awful result of telling her to end the affair or get out!
(Have you read Harley or Dobson?)
