Take care of myself, and make sure the road back home is smooth.
You might find - I don't know, only sharing from experience here - that once you work on your own issues - anxious attachment, control (perhaps) and anything else that comes up for you as a result of this journey - you will change, and what your W has to offer you will no longer be something you want. I think that's roughly where I am at in my journey now - and it isn't particularly pleasant. Don't be too surprised if once you've done your own growing, your wife's immaturity becomes more unattractive to you.
