Pushing themselves away?

Been in a long-term relationship and the fire is not burning as hot as it used to. Me and my partner used to be very close. But in the last year or so there is a lot of distance between us. He used to do so much for me. But I never really put much effort back into him. Feeling like the relationship is going downhill. Maybe me being selfish pushed him away.
