Confused by WAS

[Grizz]

Well wife had been in another room for the past week. Returned the past 2 nights to our room. Long story short, we ML last night. Contact initiated by her. Afterwards however she cried. Conversation as follows:
Me: what's wrong
W: nothing
Me: do you regret doing that
W: no
Me: then what is wrong
W: I don't know
Me: do you want to talk about it
W: no
End on conversation. She falls asleep up against me. She has not been as distant today as in the past following ML. Not sure what all of this means. I have said it a hundred times and will probably say it one hundred more but I am so confused. I will say that I am definitely more emotional since last night. That really hurts the detaching progress. But I have not pushed or asked anything today. Not being clingy.
Sandi if you read this I would love your take on it since you had some insight on the sex topic before. Also, anyone else that would like to offer some insight please do. Good luck to all.
