The Sacred Hearth

I fail to see how your husband's mistress's national origin is relevant, but I will refer you to http://www.sacredhearth.com/bos/rituals/spells/remneg where I have outlined a spelli that should help you.
But please remember to focus on yourself, not other people or their nation of origin. You can't do what is best for yourself when you're busy worrying about what other people are doing.

If you'd like more help or a look at the cards to clarify what's going on, call me at 1 800 ASK KEEN extension 0407070.
