my wife left, but still lives with me

[tough spot]

My wife said to me two days ago, after a couple months of discussions about where our relationship was going that 'she feels disconnected from the marriage and is done'. I asked at that point where we would go from there and she responded that 'she was ok with the living arrangements'.

We have gone to marriage counseling twice in the past, both times gaining something, mostly on how to communicate better. The first time she basically sounded like she does now, the second was more the result of an EA/internet deal with one of her old boyfriends.

I have read DB and am trying to integrate that into my life by GAL and detaching. I haven't resorted to any pleading, rationalizing, or basically any in depth discussions. I am now even wondering if it isn't best that we do split. Pretty confused, pretty upset, pretty unsure of what to do next.

Just now she went to bed but before she did she held out her hand for me to hold for a moment. What does that mean? We also scheduled ourselves to go to a christmas party next week that we have always went to in the past.

It is like the same life but without sex and seemingly no future. Very confusing. Not sure if I am detaching by avoiding relationship conversations or being a doormat.

Any input would be appreciated.
