Sorry you are here but its a good place to be in your sitch. I dont post much, but just wanted to say yor W sounds very much like mine. Some of the things you posted are pretty clear signs there is a OM involved. Password changes, no desire to do MC, and the old "I dont want to be a wife or mom anymore". Search for puppys posts on busting the A or letting them go. If you really dont care anymore (something tells me you do or you wouldnt be here) then letting go is your only option.
If not, then as painful as it might be you need to find the truth about OM and go from there. If you have read alot of the sitch's here you learn the WAW "script". Its amazing how we are all different but yet the WAW script remains the same. If you can search for posts by puppy dog tails, robx, gucci loafer, coach, greek, sandi2. IMO they will help you the most.
Best of luck to you..
