Waw came back to me but now what?

[kevinlost]

Well W went out with the girls tonight. I support girls night out. But I just got a text that she's too drunk to drive gonna sleep at friends house. I am really upset. Today has not been a good day.
W told me today that we needed to separate and that me moving to keep my job would be our separation because she isnt moving with me. just a week ago she wanted to save our marriage and was willing to move with me. Now she says that we need to separate because she cant get the time she needs living together.
I am so bewildered and confused. I feel like she just told me she wanted to work on things so I wouldnt kick her out, so she wouldnt have to be out on her own. Once things settled down she is going back to her old ways again.
She talks to the OM all the time. She checked her email at least 10 times today to see if he wrote her.
I love her but at this moment I would sign the d papaers just so this all would be over, but it wouldnt we have a child together and we will be in each others lives forever. If it wasnt for my son, I would just give up on everything. I grew up in a divorced home and I dont want him too. I never had a male role model in my home for me to look up to. Just a worthles father who if his schedule wasnt too busy I might get to see once a month.
I know that if I move to save my job and my W doesnt commit to saving our M, I will never get to see my son. I will be living 800 miles away. I love my family more than anything in this world but If I cant have them I dont know what I will do. My job and my work schedule change constantly so I would never be able to keep my son, so I will always be at the mercy of W to throw me a bone once a year to see my son.
I want to save my M, I have worked so hard over the last 5 months and thought that I had made it. I thought that we were going to be ok, but now I am ready to give up. I cant allow W to break my heart anymore by her actions. Not comming home tonight just makes me wonder where she is. I dont know. She wouldnt even give me a number to call in case the kids got hurt. She has 3 kids from her first marriage.
I think I am going dark. No more loving acts of kindness. No more backrubs, No more rubbing her head to go to sleep. No more complimenting her on how good she looks. Nothing.
Time to divide up the furniture.
I am moving in about a month.
I need help I think I am about to give up completely!!!!!!!!!!!!!!
