CBK I can feel your pain...I remember it so well...my H was pretty much like your W...said he was happier alone then with me...the OW didn't last long after I discovered the A but he still didn't come home...still didn't want to give us another chance...still didn't want to be with me...it hurt...I slept very little too...then one day the roof fell in and I started sleeping like a log...it took a long time but eventually your body will get what it needs...just be careful...this is a time when your are most vulnerable...I can't tell you how many I know (including myself) that get traffic tickets or have an accident during this time of turmoil...try and keep your focus when you are driving...know your limits...if you are too tired then don't do it... It does get better...it does take time...and patience...work on this in your everyday life...you will be a better person in the end for all of this...
