Wife just told me doesn't want to be married

[witz10]

Well as of right now I am done with busting. My W and I were emailing back and forth today about our soon to be separation agreement. Tonight when I was over at my condo tto be with my kids cause she works late on Tuesdays I confronted her when she got home. I looked at her and got a little emotional and was not going to say anything then I turned around and came out with is there another man? Her response was do you really need to know. I told her according to my therapist I have a right to know. Her response was I consider myself single.
Now according to her she is not filing for divorce. Then I asked her do I need to know anymore? Her response was No you don't So I said ok youare sleeping with him. I have mentioned this piece of work in previous posts about how he drinks a case of beer a day practically. This is what she is doing while we are separated. Friends asked me would you take her back and I am not sure. My heart says yes my mind though. Could I get over this. I don't know.
So divorce Busting world what are your thougths to my situation?
I am speaking with my own attorney tomorrow.
