Infidelity is an unskillful coping mechanism. Any other story is built on the lie of wounded egos.
When I spend resources trying to avoid the painful moment I am imagining, I will never know how to respond to the actual experience. Everything becomes a story about a fix to a broken fix to another useless hole. These responses to my discomfort only create a new narrative of pain for myself and others. I avoid living in an impermanent moment out of fear.
