FY, interesting that you mention this detachment "dance" to RL today. I just posted about that on my thread! I, too, am struggling with this.
RL, I like what FY says about being detached. I have been REALLY worrying about the whole detachment thing...because my H is still at home, too. It makes it very, very hard to find the right balance.
If I detach too much, he gets upset and thinks I don't care anymore....but we do have to detach for our own sanity, too.
And, RL, I truly admire your strength and your determination in standing for your marriage and for your MLCer. It isn't easy but you are so brave. I totally get others seeing it as "cake-eating"...but you know what is right for you.
