3. "Acabo de estar en tu restaurante favorito".

First of all, he listens to you. Otherwise he wouldn’t know what your favorite restaurant is. And secondly, he doesn’t give a damn about your favorite restaurant.
He’s just using it as an excuse to enviarte un mensaje . He wants to get the conversation going because after this text will come another one and another one…and you see where this is going.
He’s only trying to find a reason to text you because he misses you.
