"A teacher is ready to help a student, only if the student wants to ask questions and seek help from the teacher."
Likewise, I am ready to accept this girl back as a friend, only if she wants to befriend me back. Wishful thinking will never get us anywhere. So..
"I am ready to welcome you back as a friend. But all I will do now is wait. If you want to come back, you know where to find me."
