I don't think I agree with a lot of this. Especially:
Do you stay because a blinding, incomprehensible mix of pain and relation pulls you close and holds you there??
-Then it's LOVE.
That's obsession. That's dependence. That's martyrdom.
I think some of us here were in co-dependent relationships before, but for most of us, we had healthy, happy homes that got sideswiped by breakdown. These extreme emotions are normal for people like us who were in shock and trauma for a long period of time, given the level of insanity we have been forced to deal with.
But now, we are growing forward. It is time for us, most of us being midlifers, too, to mature our view of love. We have all, as standers at one time or another in this, sacrificed bitterness, anger, resentment, and hatred in favor of agape, understanding, forgiveness, and empathy. We're already 10 steps ahead at getting to a more whole and rational view of love. I think working in that we should blindly accept cruel pain as part of that process (where it never was in my 20+ years with xH before) is more a result of victim identity issues than it would be commitment to a healthy life. Just my opinion!
