What I meant was, that it is easy to misstate your actual feelings to your partner. Or, simply change your feelings or your mind! Your "revisiting" allows for those options. Couples always have disagreements, then fite. They usually come to some uneven compromise. Then try to live for years using rules which may have been obsolete a week after they were set. However, neither wishing to stir the issue and start a new fite, just live with useless rules!
The problem; it only takes ONE partner to be unwilling to wade into the communication morass to change a marriage from partnership to separation. And, often both r unwilling.
