Thank you for posting, I agree with Trumpet on that you are inspiring! :-) Even though my stbx didn't come back I think if she had I would have the same feelings as you. I stuck by her side through thick and thin for 9 years and one time we had an issue which was pulling us in different directions she ran so she could feel better.
I still can't understand it at all, we had the type of relationship that you described, we too had everything and she just walked away.
I can see the effort you are making and hopefully you will get the feeling that you want back.
I don't really have any advice I just wanted to thank you for posting and sharing your story.
