Usually, if the current relationship is stable and deep, most people will focus more on their relationship with their current partner rather than past emotional or physical memories.
However, there are also certain situations, such as unresolved emotional entanglements or deep physical memories of an ex girlfriend, where occasional feelings of longing may arise.

It is important for both parties to communicate candidly, establish trust, and jointly maintain the current emotional relationship.
