<human>: Could you distill the essence of the text into 1-3 sentences?

Without getting too much into the details, my parents have been in fights (really inconsistent and with varied room inbetween fights) with each other over the last two to three years, and i think they are reaching a point in which they've noticed that they might actually break up. They've been together for about 22 years, married 12, and they've always loved each other, in spite of their differences, that i can assure you, but perhaps the latest years (which have been a lot tougher than the previous ones, due to loss of jobs, bad economics, stress, you all that shit) things have just gotten worse and worse. However, what i want to talk to you about is, what happens when your parents get divorced? I mean sure, there's not a nail in the coffin about it yet, they're still sorting this out and me and my siblings are doing as much as we can to help them, but i'm talking hypothetically right now. I think i could handle it quite well, i would be a great strain on my heart to see them break up of course, but i'm 18 years-old now, and i've got a job and could if i wanted probably even afford my own place so i would'nt have to take part in the shitfest that is a divorce, but what i am concered about though, are my siblings  (two at the age of twelve one boy one girl, and one at the girl at the age of sixteen) what will happen? Let's say they do break up, this would kill them, really, my sisters were crying their eyes out tonight when the parents were fighting (which in turn led to this post). I can't leave them if the divorce actually happens, no way in hell, so how do you deal with it? How do you deal with your parents breaking up? I've had to take a extremely grown-up stance in all this to comfort my sister but i'm getting torn apart inside, i don't now if i'll be man enough to take care of them, i just need someone to talk to that has been though this.
<bot>: Parents maybe getting a divorce, i'll live through it, my smaller siblings won't take it as well, what the fuck do i do?
