People who have been in a non-cheating-centric relationship, how did it go for you?

Let me explain: A non-cheating-centric romantic relationship is one in which both partners place an excessive emphasis on the issue of fidelity, often to the point where it dominates their communication and behavior towards one another. This type of relationship is defined by a heightened concern and focus on maintaining faithfulness and avoiding infidelity, sometimes at the expense of other important aspects of the relationship such as emotional connection, mutual support, and shared interests.
