I'm gonna get back at this woman.
Did she do something to you?
She had slept with my husband.
I can understand why your angry at this betrayal. You should be mad at your husband, too. But revenge is a destructive emotion and does nothing to remedy the situation.
We're planning to take her life and make her a sex slave
You need o step back all reassess the situation. Hurting this woman doesn't undo he cheating, and your husband is just as guilty in this.
