First Post--2d troubled marriage

[2X Divorcee?]

So, my DBing has included some pretty good GAL stuff. The distance and timezones automatically helps to detach. PMA is normally intact (a couple of down days)but the whole D papers stuff is hard to take. I have not reached out to any of her family or friends but that takes some real restraint too. Not sure I really have any 180's except for deciding to contact W or not contact W. Right now, I think I will continue some calls even if it is annoying her. I think the annoying is just that she has to admit I can be a good and reliable friend...even in hard times.

Here are some questions if anyone wants to share some thoughts:
Any thoughts on giving this a name (MLC/depression/WAW/other? I'm honestly a little confused given all the info I'm reading or advice I'm getting and trying to apply.

Should I read "Decoupling"? I read a couple of posts saying it was a good book. But my quick read of the introduction didn't make it sound "pro marriage"...?

Thanks
