lost, Trapt gave you a very good description of the confusion and the walkaways. Confusion runs very high, right along with the depression, during a crisis. That's why it is very important to keep your expectations at zero. These folks are running on emotionally craziness and are not thinking rationally. You cannot expect someone who is emotionally all over the place not to be confused. They do not know which end is up. They are hurting very badly and they do not exhibit scars, cuts or bruises on the outside for us to see, but they are on the inside, they are in their heart, soul and brain. These wounds have to heal before they can become better and more mature people.
Step off his drama train, get your feet back on the platform and detach more. The less you get sucked into his drama, the less you will have to be bounced against the wall during his confusion and depression. Focus on you, what is important in your day and your family. They are your stabilizers for right now.
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.
