Prayer for a miracle in my relationship

Dear God, I pray to you to work a miracle for me in my relationship. It is more than a month now that he has left me telling he is unsure and this wont work. I love him a lot and need him in my life. Please God, grant my wish, fulfill my prayer so that he will come back and accept our relationship and we can start a new life together if it is in your will. I trust you will hear my prayer and I will not stop until you give me this miracle. I do not know how to write perfect prayer but you know what I want and i trust you will give me. Thank you..
