From what your W says, it seems as if your chance of reconciliation will be linked to living separately.
You are saying it might make you guys drift farther apart. yet it seems as if she is saying IF there is a chance, it's only if you live apart for a while.
The longer you try to cling, the more resentment that will build. And you say she says she loves you, but has lots of resentment.
So, do we cause more resentment, or do we move forward (like sotto said, forward moving does not mean dating) and build a life for ourselves giving a chance for your wife to get rid of some of that resentment and you can lose your fear of being alone and become your own man that is not attached to someone elses identity?
