Been there and done it, man. It's not a fun place to live.
I ended up getting a divorce, which I never recommend to anyone. That's no fun either, especially if you have kids. I just got to the point where I finally accepted that she wasn't going to change and I didn't want to spend the rest of my life miserable. Hopefully you're not there yet, and you've got a chance to work this one out. That's highly preferable to the alternative if you ask me.
Since every situation (and person) is different, and I don't have two hours to sit here and type... I won't try to offer blanket advice, other than two simple things:
1. I agree with the marriage counseling advice. I had never been to a counselor before in my life, but my first wife and I went to try to 'save the marriage'. She wouldn't participate (she would bow up every time the counselor said she had any issues, or that we both should share blame and responsibility, etc) and finally she just refused to go, so it didn't save the marriage, but it helped me. I don't know if it was that particular counselor or that it just helped talking through things with a third party, but I kept going to see her even after my wife stopped. It was really good for me, and I think for sure helped me be a better person and husband to my second wife.
2. You should read "Love and Respect" by Emerson Eggerichs. It's a Christian-based book, but he puts everything in practical terms. My 30-second summary is, women crave love and men crave respect, but neither person is born knowing how to communicate it to the other person. This leads to a crazy cycle that has to be broken somehow. That may not sound like some big revelation, but his theory is that it's the root of most issues in marriage. It's a really good book.
Good luck my man, and keep your head up, because no matter what happens, in about 5 years you will be over it and life will be different and most likely better.
[Side note, this was not what I expected to read or post when I logged in this afternoon.]
