I'm betting on an understanding T.
Issues with the T's spouse often come up. It's difficult to accept the T's role in our life, where it really is, and how to create that spot for T (which isn't like anyone else's at all.) Don't worry, you aren't the first patient to need to discuss this, and you won't be the last. Go for it!
I think turning in the poetry was a wonderful effort on your part to help your healing process. I hope T is able to understand such writings and glean from them more ways to help you.
