@Mary96,
Tell him you have to think about it. Then ask your heart-
Do I really love him?
Does he make me feel loved?
Does he want to come back to stay?
Do I want him to come back to stay?
Did we have problems that have been resolved?
Did we have problems that can't be solved?
Do either or both of us need to forgive the other?
Can either or both of us forgive the other?
Were we happy?
Am I happy that he wants to come back?
