That's why you need to leave him alone so he can learn to stand on his own two feet and start making a life for himself,without you in it.

Leave him be saho. I was one of the ones to tell you to leave in the first place. Just do not talk to him. And I say this for him, not for you. He thinks he needs you and he is going to cry and beg for you, but with time, and no contact from you, he will come to understand that his heart beat is not dependent upon you. He will understand that he can live without you. And it is going to be stressing to you, I know, and I am sorry, but this is the best way. I promise you, it is the best way in this situation.
