How can one forget painful memories of past harassment, and does the questioner's current husband deserve her despite these memories?

You must ignore these whisperings, for as long as you are upright, you are worthy of a righteous husband. Repentance erases sin, and one who repents from sin is like one who has no sin. What happened before puberty is not held against a person, for the Prophet, peace and blessings be upon him, said: "The pen has been lifted from three... and from a child until he reaches puberty." Beware of being carried away by these whisperings, and focus on what benefits you in your religion and your worldly life. Increase your remembrance of Allah and supplication, for they have a great effect in getting rid of whisperings.
