Thank you very much for your wise words. You gave me a lot to think about. As for contesting my divorce, I have not, at least not recently. As difficult as it is, and as you suggest, I have been trying to just let go. Part of my reasoning for this is her willingness to grant me full custody of our boys. The boys want to stay with me, in our home (I'll have to buy her out). If it must happen, this is about the best way it can go. Also, as you said, the MLC timeline appears to be much longer than the legal one.
For years I always looked at my W as "the rock" of the family. The one who did so much and helped keep so much organized. However, since MLC set in, I feel I am the more grounded, so to speak parent, and am better able to keep the boys. Maybe she feels this way too? She won't admit it though.
