How can a wife overcome her anger and sharp tongue towards her husband and his family, given her feeling that her husband neglects her and her desire to live a happy and stable marital life?

It is a mistake for either spouse to tell the other about their life before marriage, as reality has proven this idea to be a failure. What happened before marriage should be left in the past. If it was a sin, then repentance erases what came before it, not informing the spouse. A believer is commanded to conceal their own faults. The Prophet, peace and blessings be upon him, said: "Avoid these foul deeds which Allah has forbidden. Whoever commits any of them, let him conceal himself with Allah's concealment." He also said: "All of my Ummah are forgiven except those who publicize their sins." The wife should show interest in her husband and change her lifestyle to break monotony and avoid complaining. She must also control herself and avoid anger and a sharp tongue, as these destroy marital life and can be the reason for her husband's aversion to her, along with turning to Allah in supplication.
