Does a mistress ever physically attact the wife?

There have been all sorts of unplanned consequences resulting from an affair, besides STIs and pregnancies. In some affairs, the other person becomes a stalker or blackmails the cheating spouse; the affair partner (other woman/other man) harasses and threatens the betrayed spouse, the betrayed spouse harasses the affair partner. Even worse, there have been murders and suicides as a result of an affair. There's no way to predict what person will be set off by the results of an affair.

ANSWER:

AS far as I know yes there are some mistress that do no stop harassing the wife. I'm not sure how dangerous a mistress are, but I will use my past experience. When I discovered my husbands love affair, it automatically changed their life together. She said I ruined her life with my husband, and some other stuff. To me it's my husbands fault why she become this way, even they met on a dating site, it was him who pursue her even if she was still married. And because he fell in love with her but unfortunately I discovered their affair, he stop seeing her.

That woman still part of my life even I don't have a life with the man that I married. But this is what the mistress is been doing, to make my life with my children miserable.
