Been looking at your 6 stages of MLC and feel that C may have already been in MLC when we got married 2 years ago. in the first part of our 2nd year was already into state 3 - Replay. That is when she got her tattoo (little butterfly and later got her belly button ring). And I believe that stage 3 and 4 overlaped alot.
I will continue to be her friend - just let her know I am there even if she does not feel she wants any friends now.
