Nature Lover, I have never been in a room with 1000 people where I was the only divorced one.
Where on earth do you hang out?
I have been in many a room, where I was part of the vast majority of divorced folk, and I only have one (1) childhood friend that is still married to the man she married 42 years ago. All my close relatives are divorced and from the extended family, about half of them. Of the non- divorced ones, many have never been married.
I hadn't realized how extended the situation is, until I read your post and took a count.
Bad marriages happen a lot, and for the last several decades, people decide to part company instead of suffering with one another.
Let go of the idea that she will come back, you are only torturing yourself, and maybe you will eventually find a companion to share the beautiful (and the less so) days with.
Cheers!
