Ynadin,
I get it. I truly get it. I'm trying to move on so you'll see me use words like " I dont want to analyze it or ruminate".. Fact is everything you say..all those aha moments are most likely true. What I found is it can overwhelm you; in a sentence; if you look back now with all you know now, you/we can see just how horrible our spouses were...how things were the way they were because of them and their secret".
What I like to do is what my therapist told me; look back and process...maybe see the aha...maybe ruminate.. but only for a finite time...say 5 to 10 minutes. then jump back to the present and do something useful.. This helps by reminding me it really happened but does not overwhelm me with grief.
We gave true, fierce, authentic love... we were all in.. they were/are not ..they kept some secret..some portion of them held back.. its a cruel selfish thing. I look back with pride instead of shame.. I look forward with some hope of knowing my past for what it was...knowing I was authentic.
