Sometimes I think the problem is we detach so far, learn to accept the loss of our marriages, GAL, start to love our lives "even without the spouse" and then when they come back it's not so easy to "reattach." We think, "Hey, maybe life would be better without this person who caused us so much pain...."
I do understand where you are coming from. I find myself struggling with the same thing. I'm not sure the answer. I think it's important not to make quick decisions (especially out of emotion), and take the time to think things over carefully.
There is no arriving, ever. It is all a continual becoming.
