Ya sorry i read it wrong. But that does not change the fact that this guy straight up told you he is not looking for something serious and you ignored that and slept with him anyway in the hope he would change his mind. When someone tells you something, you should LISTEN to what they are saying and not go off on your own fairytale of a happy ever after in your head..
Its simple. You tell him how you feel and what you want. If he doesn't want the same thing-you move on and don't become a co-dependent doormat that he can use
"Don't ask a question if you can't handle the answer".
