However, I do think that your xw is finally settling down a bit and as time moves along, I may be wrong, but I think this new baby will heal some scars in both of your hearts.
Enjoy your weekend and take lots of photos of the wee one.
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.
