Hello 41singleBNE, thanks for getting back to us.
Yes, I know this feeling even though I was the one that caused our divorce and it took me a few weeks to finally understand what had actually happened, the person who I was married to for 25 years was no longer with me, the person I had always wanted and expected to be with me forever was no longer there.
I know this sounds to be ironical but my depression slowly improved and I don't blame her one bit but finally, I made contact with her and now we speak regularly, maybe twice a week and talk as if nothing happened and this could also happen in your situation, however, if for some reason something comes up that may trigger a concern, one of us says 'to move on'.
Unless both of you are able to cope with going back in history and want to do it, take it slowly.
I hope the two of you are able to recover from this.
