What Puppy said to you is true Mark. When women check out of a marriage they tend to rewrite history to justify their decision. When you said that your wife told you the problems had started 2-3 years ago was that something she made you aware of at the time or has she just told you that recently? As Puppy says, there's a huge difference. Do not believe half of the things your wife says to you now. She's going to be saying things to get a reaction from you. Don't rise to it.
When I mentioned her trying to call your bluff in my last post I meant that you need to stick to your guns. If you talk the talk you have to be prepared to walk the walk. You don't just have to act more assertive and manly, you actually have to be more assertive and manly. If she sees the change in you she will try to test it. If you're not commited to the change she will see through it.
Don't believe your wife when she says it's too late. Divorce Busting can be initiated by one person only. If you can stretch to it financially get yourself some telephone coaching. They'll give you a much more personalised plan of action. I just had my first session this week and I found it really helpful.
