I agree that being cheated on is painful. But sometimes those emotions are fueled with “ego” and a skewed sense of what we “own” or are “owed.”
I’m not saying we don’t feel them, or that it would never hurt — it still will. I’m only suggesting that part of the healing is understanding that they are their own person, and will live their own lives. The only thing we control is our response — respecting that helps over time.
