Relationship experts warn of subtle signs undermining long-term intimacy

Experts suggest that long-term relationships and marriages can be undermined by subtle, often unnoticed behaviors rather than major conflicts. American sexologist and therapist Dr. Tammy Nelson notes that a loss of curiosity toward a partner is a significant risk factor. The misconception that one fully knows their partner can lead to a decline in attraction, as individuals constantly evolve in their preferences and visions for the future.

Psychologist John Gottman highlights the importance of emotional connection through small, everyday interactions. He describes minor attempts at connection—such as sharing a thought or pointing out a sunset—as vital moments. When these attempts are met with silence, lack of interest, or distraction by devices, it can lead to a sense of loneliness and emotional distance, even when partners live together.
