The spark can be measured. And rebuilt.
Couples often say the spark just faded, as if chemistry were weather. It is not. Chemistry runs on specific, renewable ingredients: playfulness, courtship effort, security, shared newness and daily touch. When it fades, one or two specific ingredients have run low, and refilling those changes everything. This assessment finds yours.
Answer about your current relationship, from the frame of the last four weeks. Best used the way chemistry works: both partners take it separately, then compare. The gaps between your two reports are the evening's conversation.
