One of the most important aspects of life is the ability to forgive. It takes a lot of courage to forgive and one who learns to forgive learns to love and make any relationship work. It is said "To err is human and to forgive is divine". How true, for only forgiveness can make you understand what love really is.
On forgiving and Forgetting
When you forgive you do it for yourself. Forgiveness is a gift you give to yourself. It is not something you do for someone else. You give yourself peace of mind and it makes you a good person. Refusing to forgive by holding on to anger, resentment, and a sense of betrayal can make life miserable. There is nothing so bad that cannot be forgiven. So don't hold on to the anger and resentment but let go and you will be much happier in life.
A healthy relationship with anyone is not possible without forgiveness. If you have been hurt in your relationship then it is not possible to enter into fresh relationships unless you have learned to forgive. You cannot have a loving and rewarding relationship with anyone else, much less yourself, if you continue to hold on to things that happened in the past.
Living with Love
Regardless of the situation, making peace with past love partners, your parents, children, your boss or anyone who you think may have "done you wrong" is the only way to improve your chances of a "healthy" relationship with yourself or anyone else for that matter! It is not possible to truly be present and available to a new relationship until you heal the hurt and upsets of the past. You can never live in the present and create a new and exciting future for yourself and your love partner if you always stay stuck in the past. Remember there is no future in the past and all the love awaits you in the future.
Forgive and forget is a myth. You may not forget but you can choose to forgive and move on. With time the hurt and the pain will fade. Forgiveness cleanses your system of the poison that will surely worsen and cause sufferings and continued misery if not released. Don't poison your mind with resentment and anger. You cannot take the poison and expect someone else to die. Those who have wronged you will go on with their life and you will be the one who will continue to suffer. So learn to forgive and move on with your life. Remember you deserve to be happy.
