I feel my situation is slightly different from many stories I read from here. In my case, I think I deserved it. Although her way of showing this to me is a bit extreme in my opinion, I indeed failed her to be a caring husband and father.
We all fell short in our duties as spouses or we wouldn't have ended up here to begin with. But, our spouses share in the blame as well. The problem is they don't see it that way, at least not at first. They want to heap ALL the blame on us. They will rewrite history and say things like "I never loved you", "we never should have gotten married", "I was never happy". It's all part of their defense mechanism to help them believe that what they are doing is right.
So what do you do, well you quit pushing her and pressuring her and talking about the R. Give her TIME and SPACE. That doesn't mean be cold and uncaring, it just means remove the pressure from her. Don't try to get her to sleep in the same bed, don't talk to her parents about the sitch, don't be all passive/aggressive to her. Read DR, read Sandi's rules, read all the links Cadet posted. Incorporate what you learn into your life and into your interactions with your W.
As you change your W will think they are tricks to get her back. She's got to see your changes CONSISTENTLY over a LONG PERIOD OF TIME before she will start believing they are real. So the key is doing 180's and doing them consistently over a long period of time, and eventually making them permanent.
Good luck and welcome to the forums!
Your English is great by the way, there's no problem understanding what you are writing.
