Everything that's been said ^^^^^^^ is true. I am so sorry. We've all had the same thing happen to us with our MLCers. Being Me had a point, the better the marriage originally the worse the MLC. I do believe that's because the MLCer has to dig so deep to find excuses to leave yet all they can come up with is pea sized situtions and try to work them up into a mountain.
Everything your H has said to you, I heard too when mine left. We call this the MLC Script. Detatchment is key and the best way to survive during this.....but probably the most difficult for us LBS's especially if you still live in the same house or have alot of contact.
In the links cadet sent to you, the very last one From Withdrawal to Acceptance really is a good one. There are posts in this thread from an MLCer himself that gives you up close and personal insights as to the MLCers thoughts and how they rationalize their situation. I know after I read this over I felt alot better and in a way worse. I felt better because I could see just how irrational their thoughts were and how twisted their thinking becomes. What made me feel worse was that these MLCers are so confused and so overwhelmed with emotion that they really are in pain, but the path they choose to numb or attempt to heal this pain is destroying the strongest thing they have which is their family.
