The critical part is to discuss boundaries. Know what is okay and what might be considered emotional infidelity. When my ex started sharing deep concerns about her marriage to a handsome, younger, colleague she was essentially letting off steam, getting support, and giving this “new man” a good bit of her emotional energy. It was the beginning of what led to the end of our marriage. It was a pattern she had repeated. It was how she landed me in the first place, having “lunches” with me while still living with another man.
