I am here to tell you that you should just let go and move on. Forgiving and forgetting is not easy at all, don't let anybody lie to you, but when you choose to forgive and forget, it is one of the best thing in life.
As this new month begins, decide in your heart to forgive everyone, forgive your love ones, forgive your husband or wife who has cheated on you several times, forgive your father who was never there for you as a child, forgive your dear friend who betrayed you, forgive your colleagues who set you up, forgive everybody no matter the crime and trust me life will be better.
Take care of yourself and have a blessed, fulfilled, fantastic new month. Ciao
