Jde, this stuff is difficult. Other than serious health issues, this will be the most difficult thing you will go through.
However, this is not a competition. So what if she appears happy. Do you really think she would let you see if she is unhappy with her choice? It will take a long time before she can admit to herself it was a mistake, let alone to you.
So yes, the answer is to DB. The answer is to put big-boy pants on and not sit and feel sorry for yourself. We had a poster here a few months ago. His W left him for another guy, then took out a TRO on him (by his own admission he punched her car as she drove away). Poor guy would sit and stew in his own juices every night.
