I would try to remember too, that your T is in the same situation you are? She doesn't know your husband at all; what if he asks a hard question of her she might not be able to answer or causes some sort of scene? She's there for you, and if he says/does something that threatens your well being she will have to step in to help you!

You're actually in the "best" seat because you have associations to each of the other two, you and T are a pair and you and your husband are a pair; each pair has individual, shared stories the other person not in that pair doesn't know about. They can't "gang up" against you because they have never worked together, haven't even met each other!
