Sorry you feel that way.. I've been S from my W for 15 months I'm DB like a trooper and get the feeling it's all for nothing. I stop at work and stand there thinking to myself "I can't believe its over!"
The one thing I can tell you is I've taking great comfort and knowledge from these boards, it really does make sense to just go out there and enjoy YOUR life. Sure your W left you for a reason so try and do 180's on them but if she sees you enjoying yourself, your life she may just jump back on board?
Good luck
