Hang in there. None of this is a guarenteed fix for your marriage (M), but if you do it it is going to minister to your life and help you ride through whatever happens much easier.
My advice to you is read, read, read as many posts as you can. there are others on here who have succesfully saved their M and there are a great deal of folks trying. Either way, you will come to understand yourself and her a lot better than you do now. I'm not the most experienced, so the advice I haveis mainly about taking care of yourself and doing the research. There will be some folks who will post on your thread here who are pros at this. listen to them they know what they're talking about.
Also, stick with the coaching. They will help you a lot.
Good luck. YOU can get through this.
