I have no idea how to explain my divorce decision to my family.

We have officially reached the end of the road; I just can’t take it anymore. There’s constant fighting and noise, and everything is over in my mind, but when my parents talk about divorce, they act like the world is falling apart. They are worried about what others will think. Honestly, I don’t know whether it’s right to continue a miserable marriage just for their sake or to take the plunge and leave it all behind. Plus, my spouse is still acting like nothing is wrong, but I have already disconnected from him. Please, I need some advice.
