Jon, you did a good job of incorporating some of the 5LL techniques into your convo, but once again you blew several perfect opportunities to validate. What you don't seem to get is your wife's feelings are VERY real, and you just keep blowing them off like they don't matter. "Oh sure you have issues with the past, but I can't change the past, so who cares? Embrace the future!" That's your attitude and it's ridiculous. It's totally anti-DB too.
So now your wife isn't jumping all over your two months worth of pseudo DB'ing so you're just going to quit? You say you don't want 2x4's, but you NEED them pretty desperately because you are ill-equipped to enter into another long term relationship until you do some more growing.
