"You need to gather all your strength to stop talking about the affair. In fact, it behooves you to stop asking questions about their relationship completely. The more you ask, the more your spouse will feel pressured. The more your spouse feels pressured, the more s/he will want to flee. Control yourself."
It speaks to me and I am feeling like I can be stronger and control myself.
Most of us are about as happy as we make up our minds to be.
