And if what surfaces instead is a long-standing unhappiness, a sense that you have been lonely in this relationship for years, that is worth taking seriously on its own terms rather than through the lens of someone new. A couples counsellor or an individual therapist is the right place for that conversation, not a late-night message thread.
Should I tell my partner about a crush?
It depends entirely on what the telling is for. If you are confessing to offload guilt, you are handing your discomfort to someone who then has to carry it, often for months, over something that was already fading. If, on the other hand, the attraction is ongoing, affecting your behaviour, or you have crossed a line you need to own, honesty is the only way back to solid ground. A useful middle path is to talk about the underlying need — "I've been feeling invisible lately and I want more of us" — which addresses the real issue without turning your partner into your confessor.
Is it normal to fancy someone else when you're happy in your relationship?
Yes — commitment is a promise about what you do, not a guarantee that you will stop noticing other human beings, and most people in long partnerships experience this at some point. The healthier way to read it is as information about your own state rather than a referendum on your relationship. If it becomes constant, consuming, or you find yourself actively engineering contact, that is the point to look more carefully at what is missing, ideally with help rather than alone at two in the morning.
