Although she had every right to lead her life , why she chose to live her later years in annonymity is a mystery which her daughter should share with Suchitra's ardent fans.
The answer lies in your very question. It's her life.She lived her life for the reasons best known to her.
Apparently she had always been a very private person and never attended parties nor socialised much except with a very close circle of family and friends. But while in films you get spoken and written about because of your films and once she stopped acting even that coverage stopped.So, she continued with her life as before interacting and in fact living seperately , close to her daughter and socialising with a select few of her choice ..
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
