I feel your pain in trying to protect yourself from being hurt by someone that has been your life for so long. It can be a hard realization, I know. Talked with my FT today about how it's so difficult to proceed just thinking about "me" rather than "us": that the actions I take now have to be for whatever my future holds rather than what happens in my M. The beauty of that is, doing so gives the best chance for the survival of the M. BUT... we can't do it for that reason because somehow, it's not authentic and won't ever come across as such!

Geez...life is complicated. I'm glad you are getting good advice from good people here!
