Hi Cory, sorry to hear your sitch but you seem to be doing better than most for the time that has passed since BD. For a WW I think what the veterans say is that tough love works the best. I understand the pain though, it is equal to grieving a spouse that has passed away.
Reading someone else's sitch always puts things to perspective. H did a BD soon after a business trip in my case too but before that he had started to shut down on me for about 2 months. Yours seems too extreme, but like I read somewhere on the forum the WAS is neither healthy nor capable of having a truthful R with anyone right now so there is a good chance this new fancy of hers will fizzle out soon. Hang in there and use this forum well, this is like a secret FB of all LBSs where instead of sharing fake happiness we actually share heartfelt grief.
