Someday, maybe you wake up and the conversation over coffee is that she is leaving. not an option to keep anything. actually, she's leaving but wants you to leave. pay the mortgage so the kids have the same house. etc. pay for this that and the other thing. you can stand your ground and everything gets upset in the balance of nature. Any way you slice it. it can suck and cost huge dollars.
seen some friends do weird things. I think the lawyers make matters worse. Every so often there comes a couple that just wants to split and they are each independent and dont need to bother the other any more.
