Well said, Angelica. I believe that MLC has as its core a poor ability to cope with reality, and thus the need to try on new personas, run away from existing issues, and disregard personal responsibility.
MLC is best viewed from a safe distance. If we fall into the trap of personalizing the crisis, then that is our issue to work out. This is not to say that the partners of MLCers are saints; in fact, our spouse's crisis is a good opportunity to reflect on our own behaviors and make changes to become better people.
It is wise to let go of the outcome and to continue to live, learn and grow. Sounds like that's exactly what you are doing. WTG!
