The biggest problem for most people in this scenario is the feeling that you've lost control over your life and your future.
For years you've lived by a certain set of rules -- that if you're a good wife, you can count on your husband supporting you.
Because you're married, your relationship is a source of stability in your life.
etc. etc.
When that's suddenly ripped away and you can't understand (a) what you did to make it fall apart so suddenly, (b) why the person who used to be your partner seems to have had a complete personality change and (c) why you can't seem to do anything to make it better, it is totally destabilizing.
Your brain doesn't like this instability, and it doesn't like the unavailability of a remedy at all! Its panic-inducing.
Because of this lack of control and the fear that comes with it, you desperately, desperately want to regain your feeling of control and stability.
Your brain convinces you that the quickest way to do that is to get your spouse back. If you can do that, then all the old rules still apply and there was just a temporary blip on the radar.
As a result, your brain will *compel* you to want to pursue, and everything else is a justification to allow you to do what you want.
Step back and look at some of these situations -- a person's wife cheats on them for years with several OM's. If that comes to light, a rational person would say "this woman has issues" and head the other way right? But in reality, we see time and again that the LBS convinces themselves that this cheater is the best person in the world, and they want to have them back more than anything.
WHY? Because the loss of control is devastating. The loss of control is something our brains can't process or tolerate.
If you see this in yourself, that you have lost your feeling of control, then you can come to the conclusion that this is what you need to deal with, not what your husband does or doesn't do.
