What you wrote about how you felt...well, that pretty much summarizes how I felt. My H is much different from yours in that he'd been doing work on getting past ego and questioning the stories we seem to run in our heads all the time, and I think that worked for me. He was also already a really confident man in other areas. So the bomb woke me up and he eventually figured his own stuff out...but if H had been a different person, I don't think we'd be where we are today.
But it's scary the thoughts that you captured. The, "What's wrong with me?" thought...the wondering if it would be different with someone else...yeah, spot on.
