Yeah, I think we've all been there. Even though we truly don't want anything like that to happen to anyone we know and care about (or have cared about in the past), in the case of D, it certainly would make some things much easier.
Another angle to this is it can also work the opposite way... for example, when my husband first filed for D, I felt so devistated I wanted to kill myself. One thing that really helped me to work out of that was to realize... Hey, why should I make this any easier for him?!!! Sheesh, he'd get the house, not have to pay child support or alimony, keep all his retirement... etc...
No way was I going to let him do that!!! Heck, I'd stay alive even if just to spite him!
There is no arriving, ever. It is all a continual becoming.
