Thank you for replying!
I feel so sad for everyone dealing with a partner who can't/won't/doesn't accept their systems.

I don't want his therapy to make everyone go away. That's all up to them and our T...All I want is for him to be well and happy. I don't think that "well" HAS to mean that the system dissolves. If they all decide to continue working together, that's fine with me. I'd like to see them working together more (better communication, more cooperation) because I see that the fragmentation and separateness contribute to a lot of the problems Jon has had.

It also creates a lot of confusion - not just to me on the outside, but to all of him on the inside. I've gotten calls from Jonathan before:
"OK, where the $%#& am I? What's going on? What happened?".
I'm at work; I don't know. Where are you?
"I just got here! It looks like I'm in some alley somewhere."
Some alley somewhere...does ANYTHING look familiar?
Travis:
"I'm scared. I wanna go home!"
Jonathan:
"Hey, kid. We'll get you there. I just gotta figure out where the $^%@ we are. Kendyll? You still there?"
Still here. What can I do to help?

And there isn't anything I can do...It scares me sometimes.
I love him. I love them. I love him all.
Thanks for listening.
