i have gone through something similar with my bf. So i get the confusion with it and it sucks i know. I would say leave him be let him cool down talk to him kinda like a friend but not to much like a friend flirt a bit but not a lot. Give it a week or 2 then tell him hey i still love you and i still want to be with you apologize and mean it take responsibility for your actions or what had made him mad. Move on from it don’t talk about it agien and grow.
