First of all, I hate games myself. Never played them... Don't even know how to be honest.
So, I would not have answered his text last night by saying "next time". Not to play a game... just because I wouldn't have assumed there would have been a next time.
He said he had a nice time. I am sure he did.
After R and I had our first date...and there was clearly a deep interest on both sides...I didnt hear from him for a few days. I was fine with it, to be honest. I mean I really liked him, but, I was good either way. I had just met him. My life would go on. When we were talking about it months later...he said he just wanted a little time and space to think about me and make sure he took things slowly because he knew the potential.
Tonight the teacher texted you, flirted a little, shared a pic...all good things. He doesnt really need you to give him hints about a next date. If he wants one, he will ask. If he doesnt right away, doesnt mean he doesnt want one.
But you are getting yourself all upset already. Which you seem to do. And I am not sure why. It was one date. He showed interest afterwards. He is taking it at his pace. You either let him or you dont.
Take a breath. Slow those thoughts down. Leave him to his .
