Have y'all seen your parents go through the process of falling out of lobe and hating each other?

So like... My parents were very all in love before I left for college. It was all so chill. I've returned home from university about a year later and now I noticed that they both fight every day .... Like every single fucking day. That's depressing cuz ngl I have a dysfunctional family. So the mood of my dad controls the mood of the entire household. All it takes is my dad shouting for the entire environment of the home to go absolutely shit. And it's been like this ever since I came back. Idk what is happening or what their problem is but i fuckinf hate this soooo much. Anyone else going through the same or been through the same?
