Rascal:
CindyC is right! There is a kind of fog that those who betray their spouses go through. On the Marriage Builders web site, they will describe this fog perfectly. You will be amazed at the similarities between the things wayward spouses say.
This fog is a type of temporary insanity. Best way to describe it. It thrives on illusion.
Yes, she is free to leave you. But if she continues an inappropriate relationship, you are free to expose it. The purpose of exposure is not to hurt or seek revenge, but to put the relationship in the light of day, so people can see it for what it is, an empty cancer on the real relationship, which is the marriage.
You have to the right to say,“I want to be married, but if you are going to share a house with me, these are the rules.” In saner times, these rules would be understood by all. In these times, we have to define them, and in some instances, fight for them. One woman I know once told her husband that if he ever hit her, even once, she would leave. That is a good boundary. Now it is time for you to set boundaries with your wife.
With prayers and love, she may come to her senses. But if you just let her walk all over you, that is not love either, and sooner or later, will not come to a good ending.
Best wishes-- i know that this is a tough time.
