Mind set:
"I can't love you anymore, I don't love you anymore. I'm sorry, I just don't want you to hope that there's a chance even we both know that there's no chance because I don't want to be with you anymore like we used to be."
Heart set:
"Let's try, stay with me until my love for you back. There's no assurance but atleast we tried to work it out. I don't want you to lose hope esp you have a problem and no one's there for you so, I'm here for you as always."
