Okay. Update. I've found the solution.

It's so simple! I'm just not gonna text him anymore! I find it easier to express myself through the written word, and perhaps that's not a good thing. He doesn't need/want to know what I tell him through text, and if he does, then he can strike up a conversation with me. But in retrospect, telling him all the things I do doesn't help our friendship, it hurts it.

And the best part about it? It's in MY power to change this!

Of course, he'll probably assume I'm mad at him for a while. At which point, he'll probably text to ask. Which gives me the perfect opportunity to tell him I don't think I should text him anymore.

Yay! Eureka moment.
