Guy I’m seeing blows hot and cold with affection?

What could this mean? Why does he text “Goodmorning 😘💕” sometimes but then other times he won’t even say Goodmorning but will continue the conversation from yesterday? He also still sends me stuff , he tags me in stuff and he even comments on all my relationship memes but is inconsistent with certain behaviors?
