Parents are fighting and planning to split.

I am 21 years old and in the last year of my college....... My mother has always complained that my father does not care for her and has total disdain for her; he prefers to be more outside the house than inside the house. But to me, my father has always been quite loving and caring. My mother was waiting for the past 20 years, that once my son is able to stand on his own feet, then I will take a decision. As I will sit for placements this year, and most probably land a job, my mother is losing her patience that she kept for so many years. During the lockdown, I have been home for the past few months and have witnessed fights happening between my parents at an interval of every 4-5 days. These days, even my father does not seem to think about what words he is saying to my mother, in front of me. In midst of all this, I have to prepare for my exams and placements too. Now, how do I deal with this situation and how do I support my parents emotionally and spiritually? Pranaam.....
