I have been going to Co Da meetings, working on myself and staying away. 
I  finally made a sincere and open amends to my exh and he cried. 
We had seen each other a few times... .  testing whether or not we really wanted to divorce. 
Our r/s had been improved- no super highs or lows, no fights. We "dated" a bit... .  ate lunch, dinner together, spent time together.
We lived, and still live in different cities.
Suddenly he wanted to reconcile... .  he told his L. to hold the divorce.
He went back and forth 2-3 times. Yes... . No... .  yes... .  No.
I waited. Stayed on my own path. 
(D is still imminent.)
Then... .  he wobbled... .  once the support money was transferred from him to me.
He waffled. He controlled (tried to) he began to subtly attack me, to blame, avoid, create more distance. 
I stayed on my path. Didn't engage in his battles. Didn't feel badly when he went off the emotional deep end. 
He jumped. (he's *done*, we're through, Not meant to be... .  sound familiar?)
I wasn't pushing him, although in the past I probably had-with my behaviors. I can admit to that.
Even with

You may ask... . Why bother? I bothered because I didn't want the divorce in the first place.
I honor the sanctity of marriage, and I felt like a trial run was in order to see if it was at all salvageable. 
Especially since I had begun the process of working on myself.
I value and trust him 
as a person... .  but as a partner he fails in emotional support. He's not able to give me what I need to feel safe, secure and cherished in the marriage. He values me for what I can do for him.
So... .  D still imminent. and I am OK with that.   

I still love him. But I don't feel the longing/clinging attachment that I had in the past. I don't need him.
That's a very liberating feeling. 
I am no longer at the mercy of my emotional ties to him. His push/pull doesn't tug at my heartstrings like it used to.
I no longer feel like his puppet. 
I guess for me detachment is Love without Need... .  Without the need to control, need to know, need to understand why, need to *be needed*. It's a stable, serene place to view the world from.
I hope he one day finds that place in his mind that affords him balance, security and safety.
I can't *give* that to him. He has to get there himself.
thanks for reading,

PS.
Wanted to add that just last week he *couldn't live without me!* and he loved me
That over the top mushy stuff was totally new and quite unexpected from my exh.
However, this week when I didn't commit to visiting on the day he suggested but wanted to visit a day later... .  the meltdown.
He made rationalizations/excuses to justify his tirade. But I wasn't fighting!
He does realize it's in his mind -this war he's waging. But he's unable to call a truce.
In the end, the disorder Rules.
