Sometime reading your stuff is like reading my own memories from about a year or so ago. My W was HUGE on wanting Family time but also wanting that hoe teenage rush that OM and the A supplied ... which as you understand will die out.
I juggled for a bit allowing her to cake eat (That and I $uck with a capitol S at this detachment thing) ... I am not sure if this prolonged the crisis, or allowed her to see that as a family we could be very happy (planting seeds). Its a struggle when you are torn between giving them a little of that drug they do actually look for us to provide while and ripping that safety blanket off them as I finally did over the Holidays.
All that being said ... you mentioned there was talk about living together as divorced ... so deep down in there somewhere she is processing options, sure that D is the thing where she will find happiness .... but at what costs ... in her head if she can still have her family when she decides to have it, be D, and have her hot passion .... she gets everything she wants the way she wants it. MLC Lala land is such a gem sometimes
You listening and validating .. perfect, presenting an ear that she trusts, she is sharing ... keep on the path, be the lighthouse.
