toxic relationships and life

being in toxic relationship for long is not healthy sign it means you are the biggest enemy of your self care and are ignoring the facts ,that God has created you for the best reasons not for the reason of everything behind you get yourself harmed,tortured not only emotionally but physically ,socially ,i really see things in critical ways in society around me and the people and those feeling pride of their toxic nature and feel happy to harming others.To be more specific a creature named “man eclipsed society”man is consider it self a biggest power ,ok with somehow,but i really felt sad last week i went to the market ,a couple was shouting at eachother for some reason and within a sec woman was slapped by her husband infront of thousands of people and it was too shocking that what kind of relationship is that ,a man is trying to develope and woman is trying to keep with this relationship for the sake of their children,but nobody cares for it ,woman should keep thinking before starting any realtionship and should must raise their voice against toxic people ,they are the serious killer if man or woman both should set boundaries for toxic .

i need your opinion regarding the situation if some one heading from one side either man or woman in toxic realtionship ,what should they do ?

Your opinions could save many lives.
