No matter what the grass is never fully greener on the other side of the fence. Both sides of the fence has rough patches.
Of course this precludes straight out abuse & cheating.
Why ?
Because somethings are just par for the course in a relationship.
Miscommunication
Balancing needs
Conflicts
No matter how perfect a relationship is you are going to experience these things.
No matter what at some point a woman needs affection and attention.
No matter what a healthy man needs to have sex.
People become resentful of each others needs but they must be met on some level in order for the relationship to work.
The challenge as well is that needs fluctuate based on life events.
It is wise that couples have a contingency plan when the inevitable happens. For example, sex may be infrequent or non existent in the case of physical illness. A man’s job or a loss of a family member may diminish emotional resources.
With wisdom these situations need to be navigates to maintain the relationship.
