Not sure this will help as I am not fully aware of your stich, will look it up. I had a similar problem with going dark, I went dark and initially he contacted via mail all the time, but it was always with a plausible reason, finances, flat, picking up things etc etc. I think he also felt obligated to ow to have a reason to meet me.
With the post above I took Julia's advice and then got in touch with an email a few days later, telling him about the concert I went to as H loves Nick Cave. He immediately responded, seemed pleased to hear from me and gave me another artist to go and see. We then had some e-mail contact but nothing had changed. he is always polite/respectful to me and will always answer my e-mails/phone calls and even meet up. We have been interacting well now for a few months but he still wants divorce.
I think in some cases like in mine - nothing works. The WAS has to go and live their life as they see fit and we have to live ours. He seems happy to be friends and I know he still cares and respects me with the actions I have seen over the last few months but he is not "in love" and there is nothing I can do about that as he is "in love" with someone else.
In this case I have done what is best for me. I can't be his friend, it is either a marriage or nothing. I think you have to decide what you want and do that. Still aim to be the best you, and GAL and 180 but they are for you. If going dark has helped you heal then do it and wait for her to initiate. But I think you need to have no expectations.
