New to this and fairly lost need help

[indigo1]

I have been married to my W for just over six years and we have a beautiful D4 together. My world came crashing down three weeks ago when a incedent she found out about set her off. Just something dumb I said to a friends sister while drinking which was uncalled for. Anyways this was what pushed her to the edge. She kicked me out and told me to go to my parents out of state until she contacted me. I spent two weeks there doing all the things I know now I shouldent have since reading DB. I begged,cried,promised to change,asked her to consided our D's future... None of this got me anywhere just made it worse. I am now back home, well in the same area staying at a friends house until I can find my own place as she is not budging on the separation.
I think I am dealing with a WAW and a MLC all in one. She says that she is no longer angry just confused and does not know what she wants or when she will know. She also mentioned that her life is half over and she does not want to spend it being unhappy anymore. She said that we have been emotionally disconnected for years now and she is scared to come back because she thinks I cannot change. I have made all the promises before only to fall back into the same old routine. Basically living like roomates I guess you could say. I can also say that realizing this really may be over has me committed to this like nothing I ever have in my life. I know where I went wrong and can go into more detail if you folks need me to. For the last few days I have been trying to limit contact to just our daughter which is very hard. I did see my wife two days ago while dropping my daughter off to her. She was at a friends house and had been crying and continued to when she saw me. She is a mess and I feel so bad, I gave her a big hug and she squeezed me tight and started to cry again. I was just supportive saying I know this is tough and tried to act ok. A real 180 from how I truely feel. So my question is how do I approach her when I see her in person? A 180 for me would be to compliment her,hug her, or hold her hand but at this time is it ok to do that??
