I am so distraught that my only apparent option is to leave... Sure, I know I can stay in the marriage, that is, if I am able to detach and carry on with my life. But, I am not wired that way. My whole sense of well being in a committed relationship is that there is... commitment, trust, honesty, reliability- from both sides. And, that's simply not the case now. So, again, the ONLY option I seem to have is to leave. And sadly, that seems like the only way to show her I am serious and give her the "keys" to her own life- however she chooses to drive it. But, the closer I seem to get to this reality, the more upset I get about the loss- never wanted to fail as a husband- this truly WAS the woman I wanted by my side late in life... never wanted to fail my kids in keeping a family together. This disease has already taken so much... sorry for the self-pity party. Thanks for all the wisdom shared by you all.
