once again, I perfectly understand where you are coming from - and I'm sure what you've said applies to thousands of WAs who are simply in a state of confusion about their own pain, which they try to project outwards towards their spouse. You sound like a person who would have been willing to work, and work hard, to make the necessary changes to improve your marriage, if he'd only been willing to meet you a small part of the way.
However, this may not be true of everyone. The members of this board aren't a representative average of the population - just the fact that you looked for ways to stop your divorce, found this message board and started posting/working on yourself is proof of an open mind, flexibility and a desire for change. Others might never get to that point, and simply ignore the warning signs, take no responsiblity for their own actions, and when the bomb explodes, assume it is "all the WAs fault" who "left a perfect marriage" just to chase the excitement of a new girl.
Each sitch is different, because people are different. But your post was very thought-provoking, as usual, and I thank you for giving me more to consider.
