Should I respond to the "other woman" or just let it go? Do you agree that she is a trouble maker?

She sounds crazy, and sounds like the kind of woman who like to live her life in turmoil. I bet her husband doesn't know what she is doing? Take the rest of this up with your husband and tell him that you will NOT tolerate his behavior any longer and that if find out he is speaking with her in any fashion, then consequences will be met. Email the other woman one last time and tell her she is sick and that you find the entire thing humorous, but disturbing since she seems so focused on you and that she should really seek out help and by the way, tell her your husband thinks she is sad! If this doesn't stop then you have much to think about.
