What is the way to get rid of the trait of harassing women, after it led to the children's discovery and the shaking of their respect, despite the commitment to repeated Hajj and Umrah rituals?

The cure for your situation is to be mindful of Allah's constant watch, to be wary of the consequences of sin, to remember that you are a good role model for your children, and to avoid mingling with women, speaking to them, or looking at them unnecessarily. Just as you would not approve of this for your own female relatives, people do not approve of it for theirs.
