I agree 100% with Heather that there is something very very wrong with these people. My xh is nothing like he used to be.
Interestingly my elder dil who knew him pre and post MLC sees a huge change in him. Obviously we do, but she was simply daing my eldest son when she first knew him and no emotional investment, as we did.
I wish MLC was better researched and understood.
Please do not assume that your xh is happy with his choices, they truly are more like addicts - driven by who know what to do these tings.
