You kiss less often than before, but you attribute it to fatigue.
He forgets birthdays, but you justify it: “Work got to you.”
But what if it's not an accident, but signals that scream about the end? Not all betrayals are loud - more often than not, love dies quietly, and here's how to notice it.

The first sign is that he has stopped getting angry. Yes, you heard right. He used to argue about you being late or leaving the light on, but now he is silent.
This is not calm, but indifference. When a person does not care how you act, he has emotionally disconnected.
The second marker is a "friendly" hug. If he hugs you like a friend (pats you on the back, avoids a long look), this is not tenderness, but a ritual. Passion is not necessarily related to sex - it is in gestures: fixing hair, stealing a smile, touching your hand for no reason.
The third sign is that he doesn't share small details. He used to tell you how a pigeon outside the office window caused a drama, but now he says, "Everything is fine." If your partner has stopped talking about nonsense, it means he has stopped putting his soul into the relationship.
But don't panic. Try a "question day" - ask only open-ended questions for 24 hours: "What surprised you today?" instead of "How are you?"
If he perks up and starts talking, there's a chance to get back intimacy. If he brushes it off, it's time to act.
