SecondChance, Because he does miss you, but not enough to come home. He's a teenager out there in the wilderness blazing a trail thru mlc. You are trying to rationalize the comments and actions of an emotionally unstable person right now.....you can't!
He also wants to ensure that you are still right where he left you just in case things don't work out and he can come back. It's the old one toe in this pond and one toe in that pond.
It's the dance...it's to suck you in and keep you in his drama, it's to keep you on the hook.
Focus on what is real and rational...you and your family. Focus on what you are doing from day to day and not on his crazy behavior. If you don't, you'll end up nuts.
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.
