I think his moving may be a good thing. If there is any tension in him (towards you), or between the two of you, that will start to evaporate. This will also allow you to truly GAL (although from what you've described you've already been mentally preparing quite well).

I can understand you getting a bit messed up by his wavering. It's hard when they waver. My husband didn't verbally waver like yours (he was 100% certain he wanted divorce for many months), but he'd sometimes do nice or loving things and that would confuse me. I think separation will help give you both more clarity. It will also give you a chance to really detach, GAL further, and maybe go a bit dark...

But {{{{hugs}}}}} to you. I know this may be difficult. If you find yourself feeling really low just go dark. I called it cacooning.

There is no arriving, ever. It is all a continual becoming.
