I agree with Painful. In my opinion it was a more hopeful situation from the beginning and based on the things mentioned she really wanted to see the change. Now this doesn't mean B didn't do any work, of course not. I admire what he did and he truly followed it through. But wanting to date and go eat in my opinion tells already a lot, and I think WASs are not the same. Some of them are truly done with the M and will not even consider regardless of the work done, especially if there is OM/OW. Maybe in the distant future (3-10 years, truly need to "find each other" again).
If truly doing the hard work would always get the WAS back, there would be more recons. It truly is doing the hard work and having the rare chance of having a WAS who is open to see the changes. I do believe a lot of us would be able to offer a better R but the WAS just isn't interested and believes it would be the same. Or they just lost the feelings. This has nothing to do with finding reasons to stop from changing, but stating the obvious. In order to recon, you need to have a WAS who wants the R.
