You burned them. Innocent men women and children yet Jon didn’t feel any hatred for you..only disappointment. He had conspired with Tyrion to kill you but could he really do it?

You and him talked for a bit it was mostly him yelling and you desperately trying to defend yourself. When you kissed him he decided it was time but once he unsheathed his dagger he dropped it and placed his trembling on your hip. He can’t do it.
