Good to see you and read how your awareness is unfolding.
Looking from the outside in, I don't see complaining... just processing. My spouse used to say I was a "go along, get along" type of person in a way that made me feel bad. And you know what.. I was. I'd rather keep the surface smooth and be troubled within rather than risk my greatest fears.
Oops.
Here's a thought to toss in as you process. Your ex-husband's decision created enormous upheaval and change.
How are you the same? How are you different? What are the most surprising aspects you've discovered about yourself? If you could go back in time to the marriage 'after the kiss' without your newfound growth and understanding knowing what you know now.. would you? Why or why not?
