My boyfriend of almost 3 years and I are in a rocky place

I love him to pieces, but I’m afraid he’s lost joy in making me happy and now sees it as a stressful obligation. I still get excited and am always thinking of the next thing I’m going to do to make him laugh or smile or just make his life easier. He’s had a really hard year, but I miss the guy that would give me raspberries just to break the monotony of everyday stress. I want that pure happiness back.
