I think IC could help you through this terrible pain and guide you in healthy steps to finding yourself again. Maybe she needs to see her own IC.

After you get through the biggest hurdle, if W is saying she wants to save the M, then both of you need to see a solution based MC. If you don't, chances are slim in making it.

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
