He gave you a taste of your own medicine huh😂. That's what happens when you give a guy who is sure of himself mixed signals. Tbh if he as serious as he sounds it means he doesn't feel the need to play the game you put on the table. And that's exactly what any man who has self respect would do i.e even though it might hurt dropping you, he dropping you and putting his effort elsewhere where it is deserved. I can not tell you that's exactly what's goin' through his mind but when the same happened to me that's how I felt and that's what i did, I respectfully dropped the connection. You can take your guess from that. About what you should do demo, let him be. Leave the man alone yo. Imagine if it was the other way around and he didn't give you the space you needed. Pretty sure it wouldn't change your mind. Now if moving on is what he wants to do, respect it and you also move on with your life. Other than that there is nothing you can do other than learn from this and make yourself better for the future.
