I'm sorry you have found yourself here...they are called WAW...and there are quite a few of us here...what you will notice is that the sits are all different male/female, young/old...but there is an uncanny way that they all sound the same... What I have discovered in my sits is that I really think that I could get back my WAW by using DBering (maybe being arraogant) but I'm not really sure IF i want her back...I really think that by reading all these posts even from the women about their WAH, it is relevant...they all have similar characteristics...and the plan of attack does not vary much...
As for the length of time...I've heard months up to a couple of years...
As for the 401k...I think very smart...I think my W is going to be in for a rude awakining when/if D happens...she gave me waaaay too much time to prepare...and my feelings are all bets are off if they have betrayed the trust and commitment of the marriage.
