T2, I think you did an excellent job w/the dinner and everything else that was going on. I'm sorry your w hid in the bathroom, but maybe it was just a bit too much fun and laughter going on for her. Maybe by going into work for a bit helped to settle her down because she needed some quite time. Whatever the reason, she should be very thankful that she had all of her "boys" there and a nice meal too.
Another one down and one more big one to come. You are doing wonderfully and I do enjoy coming and reading the progress that you are making both on you and your relationship.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
