Hey Peter, it does suk to have it confirmed but it's something I'm sure you already figured was truth(like) to some extent.
I know dbmod had cautioned the board about heavy use of 2x4s and while it's great to get sympathy, most of us come here not to get a dry shoulder, but rather to come here and DB "to save our M".
So the usual question of why did you "let" this friend tell you something you already had strong suspicions about? How has that helped you?
Second, and at your stage in the game, it should be easier now to take that time to think through your thoughts and work through your emptions before you take another step.
The rule of thumb is between 24 and 48 hours after something that creates a negative reaction before we ACT on that information or behaviour.
You may decide to move forward with D or you may change your mind, but rather than emotionally flip flopping (which won't seem like flip flop right now) for the next few days... take some time for yourself and do try to get your mind off it for a bit...
Once the emotions have settled, it will be easier to make any course correction if necessary...
