Glad you took the high road, LD You sound like you're doing okay overall, too.
It would not be fair of me to attempt to guess where your wife is at in the so-called MLC "timeline". There are two reasons for this: one is the fact that in the beginning stages of MLC, it's ALL internal. A lot goes on inside the person's head before the symptoms start appearing outwardly. None of us can know this about another person. Even a MLCer only realizes it AFTERWARDS if they try to learn what it was that happened to them. I pinpointed the onset of my MLC to starting close to a year before my husband got his first inkling anything was wrong. In addition to that, each "stage" is entered into differently for each person and many times certain "stages" are repeatedly visited before their purpose has been discovered and the person naturally progresses onto the next stage.
I am assuming you got your info about the stages of MLC here. I support them just as they were written by heartsblessing however so few MLCers come here and talk about their experiences afterwards that we just can't gauge the validity.
So while it's good that you have a loose understanding, please don't think it's written in stone or anything scientific. MLC is very much a personal journey - and mostly internal - and there is nothing you can do to speed it up. It is my opinion that a MLCer's own desire to be honest with him/herself will dictate how long this thing plays out. If she's a runner - someone given to avoidance - it could be a while. But if she's generally a no bullsh*t kind of gal, I'd venture a guess that she'll make it out quicker than someone that's prone to keeping their head in the sand.
Keep doing what you're doing and do stop analyzing (that IS what you are doing ) or you will make yourself crazy. Just to throw you a bone, I do find it curious that when your wife sees you having a great time she goes off and calls OM. But we just don't know that ANYTHING you have done is penetrating her brain right now. It is best to just look out for yourself and not make ANY assumptions about her. If something inside her head and heart starts clicking rest assured you will be the first to know!
