Wife no longer in love with me

[cam]

I know, I know - it's about me and improving myself.
I just feel like I am going nowhere. All of a sudden this situation is on my mind all day from waking to going to sleep. I am constantly going over it and blaming myself for everything little thing I have ever done wrong in the relationship that I feel caused her to walk out. I feel like I can't move on or go forward without her in my life.
It is probably compounded by the fact that she gets back from the US tomorrow so I expect there will be more action from the lawyers again and she will start progressing action.
