fluff,
I have read & reread your post several times. I keep coming back to the same place........ I think the fact that he has been so solid and dependable in his care for you over a good length of time buys him a lot of credibility. I'm sure the ativan episode was a red-flag for him. He may feel that it is time to start establishing some boundaries for you in hopes of helping you to find ways to ground yourself when you are alone. I don't get the sense that he has suddenly changed the way he feels , but rather he is concerned and wanting you to be able to have tools to keep YOURSELF safe.
My advice to you would be to write these questions and any others you have down. Very specific. Almost in 1,2,3 order. You really need to understand specifically what is happening and why now? If you have a tendancy to lose your concentration in session, this will keep you on track.
He DID NOT quit caring overnight. His thoughts about what would be in your best interest did. What you need to know is what his thinking is. How did he come to this conclusion that you have different needs and what leads him to believe that this is something you should be able to do suddenly?
He has told you the foundation is solid. This means he still feels the same about your relationship. I am sensing a real concern on his part rather than a breaking away. Try to hold on to what you KNOW to be true. Everything else right now is guessing and fear on your part. What you know is that you have been able to trust him and believe in him for a year. He is good at what he does and he has been there when you REALLY needed him.
fluff, I hope at least a little of this makes sense. I'm just free-flowing here. Love to you......and YES you are worth it. AND we were all proud of you during the last few weeks and the way you handled so much so beautifully.
