Sounds like you are trusting the process for both your daughter and for you.....such an enormous leap of faith, isn't it? Good for you.
If my husband said his lawyer thought X I would respond by saying, what do you think? The lawyer isn't the parent.
However, in the interest of co-parenting and putting your daughter first, I would tell hubby what the T said about speaking with daughter first. And then I would try to negotiate some kind of compromise with him so that your daughter's therapy can remain intact. This sounds like a good topic for the next couples session. It will probably set the groundwork for how you will co-parent from here on in, eh?
Good luck and be good to yourelf during this difficult time. We are here for you, so keep posting!
Love and Hugs.
