An example of a "truth dart" might be (these were ones that I used, so use/adapt accordingly):
-I will not hide your affair.
-I will not financially support your affair.
-It's your mess, you clean it up.
-Send him an email with STD statistics, no other comments.
-Secrets kill marriages.
-You are being played.
- Your current behavior is not helping the children.
- "No contact" means "no contact". Working in close quarters with someone who's admitted being attracted to you, and vice-versa, is inappropriate in a HEALTHY marriage. It's absolutely DESTRUCTIVE in one that's on the rocks!
- How will you be able to counsel your daughters one day if they're having problems? To cut and run? To have an affair?
- You are placing your friend before your husband, and your friendship before your marriage.
