SD, I've been keeping up with your sitch and I'm really curious at the "interesting" behaviors of P. I will definitely be watching to see where that goes.
Sorry you had to give notice to your housemate. I'm sure it was tough, plus it will be future inconvenience without the added finances. Perhaps a different housemate is an option?
I'm also sorry it didn't work out for you for personal reasons ... I was hoping I could mimic your success, whatever that turned out to be. When I read your interaction of "We had a scheduled conversation a few weeks ago. I was truly touched by his sensitivity, responsiveness, and kind approach. And not one bit of change resulted," you could have been talking about my H. You have really made some progress in areas that you're working on, and I had hoped that you could master this one as well. And then I was going to ask you for the secret formula. In any case, I hope your decision eliminates some stress for you. No need to pile it on just for the practice.
Keep up the great work! I'm hoping to read a real success story in your sitch!
