Do not allow unwanted memories to occupy your life. As it creates only pain and anger. So whatever the reason for that pain is, just move on from that point.
And if you are unable to do so, to forgive someone, then ask yourself one question,
Is this emotion serving me and my bright future?
If you will get the answer \"YES\", then continue on it.
But if the answer is \" NO\" then drop it right there, and nice on.
Remember you deserve to be happy, to be fulfilled. This is your reality.
