Is it none of my business?

[Ra77aal]

Salam,

Morally, i believe that adults are adults, and sometimes they get themselves into really big messes. Only they can solve their problems. I would advise the child to not interfere, it's not their business, they may not comprehend the true nature of the situation, and may be moved to take sides... which is bad.

Make dua for them, and let them know that you can't wait till things get better. But it's not your job or place to interfere with your parents' problems...

This is my general opinion. Of course, only you can decide what you need to do.. Good luck :)

Interfere if you have to, but don't go too far.

Remember that the deen is nasiha.

[Yaser Birjas]

The best interference you can make -after Du'aa- is to be dutiful to them. If you can be so kind to them they might always reconsider decisions just for your sake.
If one try to complain to you about the other, be positive and remind them of Allah and always show them the bright side of everything.

May Allah give you strength and power to help straighten things out.

I think I'll stick w/ the du'as.."it's" the only rough spot in my parent's relationship. I guess I should be grateful for that alhamdulillah. being their daughter I want everything to be perfect for my parents, but it can't be. they're a normal couple and will have their problems..jazakAllahuKheir.May Allah reward you for your good intentions, habibti! :)

Does that mean we should not "agree" with them?

For example: if my mother says.."how could your dad do this?"...I should not agree with her? (even if i don't agree with what my dad did)?!
