Opt - I agree on that part. I would think it counterproductive to work toward a goal while only giving it half your attention.
But then we are both on this BB because we were the ones in our own relationsips to have seen the need to change. And like the book says "it takes one to Tango". So we will be the ones to change and hope that our spouses (ex in my case) will notice and one day come back with their full attention. Until then, we can only work with the attention they give us.
