Jb - Communication can be a huge catch-all for "we have problems and I can't describe what they are." So it might not be the problem. It might be your W feeding into her narrative so she can walk away guilt-free.

But... if you admit you have communication issues, it will only help you to work on them (whether with your W, or other people). What are you doing to work on your communication? Can you be more specific on what your issues are?
