Do you think this guy is playing mind games?

I met this guy (43 y/o), and we have this unbelievably strong connection. Most of our communicating is done by text, or phone. Ever so often we'll have a conversation, then all of a sudden he'll stop communications for no reason. Nothing happens. Recently he texted me, and I texted him back with a reply. Then I don't hear from him again for a couple days. So I'll text him and say, how's your day going? And I get no response. Then I might say, is everything okay? No response. Then I'll say geez, if you wanted out, just let me know. He does not answer to any of them. Then he will send me these mysterious texts. Like he wants me to get a reaction. He'll start it out like No, but usually, and then a bunch of symbols. Then he'll say, what you didn't like it in another text? It has nothing to do with anything. It seems like a pattern with him. Today's Valentine's Day, and no Happy Valentine's or anything. Just these mysterious text. Anybody have any input? He knows it's Valentine's Day, and doesn't even say Happy Valentine's Day which leads me to believe this is a mind game.
