Eric - your advice is good, but you tend sometimes to overlook that MLCers are not rational. They really are not, trust me on that. I have some contact with my xh and so do some other friends with MLCers. They will do one thing one minute, and the next they are off somewhere else.
They act from emotion rather than reason, and they are amazingly immature. There is usually an agenda. Boundaries are important, I agree, for us. They are not recognised by the MLCer as they have little sense of what is and is not appropriate
Piecing, as I understand it, is quite a way down the reconciliation line. The MLcer reaches out a long time before that stage is reached. And it is slow.
He may not be reaching out - it doesn't matter in one sense. But simple friendship isn't usually what a MLCer has in mind, I am fairly sure!
