Marriages last whenever you see your spouse as a spiritual being having a physical experience which means that they are also on a journey of self-discovery and that in a journey there will be occasional bumps in the road.
If you truly realized and knew your worth, this fox would have not been able to get into the hen house. You were so consumed by your need for validation and love that you chose to put the needs of someone else, i.e. sex, above your own needs.
