You don't say what happened when you met up, but it would appear that he didn't ask you to get back together with him.
It sounds as if he is just making sure that he can reel you in, whenever he wants. He clicked his fingers and you went running. He may have been at a loose end or in between girlfriends. If he genuinely wanted to get back with you, then he would have said.
If you want him to stop texting, then you have several options: don't reply to his texts, block his number, or change yours.
