I think the problem you have is your W is the one controlling the times when you do things as a family. You need to say "no" more often when she wants to hang out. Maybe become more of the mystery guy - dont let her know what is going on in your life (except if it pertains to D).
What would happen if you gave the perception of the WAH? Your W might see this as a challenge to try and win you back. Doesn't the same thing happen with OM when he dates other gals? - it causes your W to only want to be with him more.
I think you are eventually going to get to being the WAH after a while of this craziness.
I agree with Sandi that you really need to try the LRT. How would you see the LRT back firing on you? I doubt your W has it in her to file for a D in the roller coaster state she is in.
Just be prepared for the next time she falls on her face and needs your help. You need to decide whether helping her just makes you a doormat.
