Scared my parents will split up

The day before yesterday my parents had a pretty massive argument - they started hurting eachother and everything. Yesterday, they weren't really talking to each other, but last night my dad got angry because someone froze the computer. Then this...

morning, I woke up and heard him shouting '..and your mother spent the day doing what she wanted yesterday!'
Right now, its nearly 9:00 and my mom put out dinner for him and he just went to bed without saying anything. I can see my mother struggling and I want to help her. I can't believe what my dad has done to destroy her, and I'm crying as I type this. I just don't want them to split up. They've had loads of arguments throughout the time they've been married and I just want our family to be happy again.

I know being in an uncertain situation is scary. You dont know what is happening or what may happen. I would think about this though. You want your family to be happy. That is the end goal. And that may happen with them being together, or it may happen when they are living apart. Perhaps the best thing for everyone is to live apart. Of course everyone wants their family to be happy living under the same roof, but that doesnt always happen. You cannot fix this situation. You can be there for your parents. You can tell them you care about them. You can do little things for them to show them that. But that's about all you can do. They have to sort the mess out themselves. And you're just going to have to be patient while they do. In the meanwhile figure out ways to keep your own sanity and peace. You cannot let what they're doing get to you. Take some time out for yourself every day doing something that keeps you happy.
