Wife no longer in love with me

[cam]

Such a tough weekend. I was supposed to be in Denver at my wifes best friends wedding, she is maid of honor. All sorts if emotions, I just keep wondering if she is feeling anything or she has just blocked it out again.
I don't know how to detach, my life is just so crap now without her, so I am struggling to see anything positive of a life without her.
I just can't believe someone can completely change their feelings for their partner of 8 years so quickly and just give up.
She keeps saying she gave so much to our relationship and she just can't give anymore and got scared that the future would be tough.
It's just such a lame excuse, but that's what she's like. Every time something goes wrong in her life she just walks away.
My confidence of saving this is just so low. I don't know how I could ever get her to reconsider or give it another shot.
I have started talking to chuck a divorce coach from here, but I have little confidence in any of the tactics working. I cant demonstrate any changes to her when she doesn't want any contact at all. It is too hard for her, so she would rather avoid it and pretend I don't exist. So how can I so my GAL changes if we don't see each other. She wont talk to any of our friends either, so she is not going to hear about me. She even asked her lawyer to state that if things get worse between us, then all contact has to go through lawyers.
I'm at a loss to develop a plan to get her back as it just feels like I'm wasting my time and money.
