Reading what you said above I have to say something...without the infidelity that I have been through, I think that your H says alot of things that my exh has said. Now, I know they are like night and day different but I see some similarities.
Maybe its an A behavior, but the giving up...not meant to be, things shouldn't be this hard, excuse after excuse was the same I heard...I bet if you look its common on the A board too.
Hang in there and keep posting.
