We all have scars from one experience or another and while you are waiting to be married, apply spiritual wisdom. If you know you cannot marry him don't waste your time dating him. If you are dating him and you realize that, then leave him. Because "the smoke you see while dating someone becomes a full blown fire in marriage."
Marriage takes more than love! love is only a fraction of it..it will not keep you together if everything else isn't in place. And if you stay together, someone will be extremely unhappy! So friends, cry about all the pains of heartbreaks for the last time if you need to, cause tears are pain leaving the body. And after that, LET GO AND LET GOD.
