If a person is in a classic full blown mlc, they will take you on the roller coaster ride from hell ... daily.
If they are really mlc, they will feel guilt, for a moment. And they will act out angrily at the source. They don't believe they should be made to feel guilty for wanting THEIR life.
Never try to use guilt on them to affect them. It is same as kicking them in the privates and expecting them to want more.
