Well done Eve and CT10 - and any other ladies who have taken the brave step to snoop and find out the truth of why their husbands are behaving as they are. Think Pramspotter and I are cut from the same cloth. Nothing makes a previously reasonable man act like this other than another woman. I truly believe that no-one can make rational decisions about their future life (and those of the DCS) without all the facts.
Once you know the truth, I do think it helps you rationalise things and I suspect that once these men have their affairs exposed, all the ridiculous fantasy is stripped away. It helps them look at the OW in a new light and in many cases, they are found wanting.
I also suspect that once you all start taking action (as CT10 did forwarding on those E mails, well done that woman!) this portrays you in a different light to your DH. All of a sudden, you become a decisive, ballsy woman in your DH's life and not someone who is waiting for a vacillating partner to come to his senses. Happy Woman says the same, I think. Once she put things in motion legally, it was the turning point needed to get her DH to see what he was about to lose.
Even if he does come to his senses, you might decide that it is too little, too late. That is fine too - but at least you will be making an informed decision based on all the behaviour that led up to the end of the marriage.
Don't be afraid to fight dirty either. This is your life and none of you should feel in the least bit guilty about snooping, contacting the other woman or any other legal means of finding out information. Knowledge is power and I applaud those of you who have made it your business to find out.
What I'm seeing in the DHs here is that once the truth is out, all the really nasty behaviour and coldness diminishes. They have started to see you as a woman with desires and feelings again. They start to miss things about you (that's why they need to chat/have lunch with you) and start to realise that actually, OW does not meet their needs in the way they had thought.
Well done to all of you for keeping things together with your DCs. You all deserve a medal - and I assure you, life will look so different a year on from this point.
A year ago (even though I didn't know why at the time) I was having a crappy time with an emotionally distant DH. Following my discovery of WHY in September, we have both worked hard to produce what is now an amazing marriage. My life and general happiness could not be more different now, a year on.
I know with certainty that this could not have happened without endless talking and honestly, as soon as my DH had me to hold a mirror up to his behaviour (and the OW's web of lies) I don't think he would have realised just how awful he had been (and how truly awful she was).
This is a long-winded way of saying "get tough and find out as much as you can". Good luck and stay strong.
