1.Nisaab is never a light matter,it is one of 5 things the sharia aims to protect ,the rights of the child start from when the mother gets pregnant, therefore not knowing who the father is, or wrongfully attributing the father is hated to Allah, not only that, but the inheritance, keeping of family ties, and the rest, is also counted in this, not knowing the father Islamically plays a massive role
2.A women spoils her husbands bed
3.A women uses her husbands blessings on her, his money, his house his clothes and food he has provided her, and used to betray her husband
4.A women cheating on her husband is much more of a disgrace than a man cheating on his wife, this is a fact of life, Islamically a women is much more protected than a man in terms of modesty, she should seclude herself in her home as much as possible, wear garments which cover her entire body, a man has intense gheerah over his women, a women cheating on her husband is much more of a shameful thing to a women than it is too a man.
5.It is contradictory to a womens nature, a women is only ever allowed to be with one man at once, Islamically, whereas a man has the capability of having multiple wives. This means in and within itself it is harmful for a women to have multiple men she is in a relationship with, whereas it is not for a man, so when a man cheats on his wife, it is a disgusting sin, but when a women cheats, not only is it a disgusting sin, but she gets the extra sin of going against her nature, and doing something that she is never allowed to do, and harmful in and within itself
