What does my boyfriend mean when he says "think of us."

Lately I've been asking him what I can do to get him back to his old self because he's become distant but not in the cheating I want to break up with you way, he says I'm self-centered and lately it's been kinda true because of stress and his lack of communication and cooperation. He says think of us but I'm not entirely sure of what he means. I'm trying my hardest to understand but I'm in a roadblock, please help.
