Because people are prioritizing their mental well being over societal norms. Because more and more women are getting financially independent, emotionally secure and they want equality in more aspects of the life.
Earlier people used to follow society’s norms of being happy and family oriented. Now, they have this realization that its better to stay single and happy than being in a broken and disturbed marriage and be unhappy.
Marriage needs efforts from both ends ,not just from one side. Also, people change with time. Getting married is a long term commitment and it needs a lot of effort, patience, sense of responsibility, trust and most of it all- willingness to make it work. If someone does not feel appreciated in the marriage and they feel like they are losing their identity, they choose to move away.
So in a way, failed marriage is not always a bad thing. If someone feels that they can live better and more freely and marriage is not like what they had expected it to be, they feel its better to move away and live as they want to.
