Sometimes when there's not much left to say the conversation just fizzles out. There's point in trying to force the conversation so some people will have short responses to let it end on its own.
This is not a case of lack of interest, there just maybe very little to talk about at that specific time
I send a funny meme condemning thier use of emojis. Showing that
1. It's not the brevity of the text that bothers you but the lack of conversational content
2. It's not a big deal. Written text usually feels more formal using a meme kind of softens it. I argue strictly in memes or in person.
3. It's completely okay to use pictures. He'll start using memes too.
Using a meme also stops you from rambling.

Just send a heart emoji and leave it at that. Don't try to force the conversation to continue if there isn't much to talk about. And ending at a point where you still want to talk will just give you something to be excited about - next time you talk/talking again.
Sometimes you don't have to, that just means he's happy. You could respond back with another emoji and that'd be fine.
