I would hope once she sees that you and your husband are a united front she will move on to something (or someone) else.

When my husband relapsed, he had an affair. I found his "secret" cell phone with calls and such. He asked that I answer the calls that camen in. (Long story) So I did. There was one woman who kept calling and calling and calling. I would answer her the same every time. "No, you can't talk to him. No, he's not here." and hang up. The last time she called she said something horrible to me, and hung up. She hasn't called again in a year.

Long story short. As long as you and your husband are united in this, I would think she would give up. Of course, some people are so unstable that they don't, but if that happens you need to explore your options as she is stalking/harassing you.

no matter what. Keep up informed.
