I can see what everyone is saying about blurring the boundaries, but what is Xtree supposed to do? They already belong to the same church and church group. It's not fair that Xtree should have to leave because T is in them. And she certainly can't make T leave, and even if she could how would that affect their relationship.

I guess the other option is getting a new T???

Xtree - how long have you been with this T? Aside from this issue, how is therapy going? Do you trust her?

You said she had some 'boundaries issues' - I assume she discussed this with you. What did she say? Did you express your concerns, like you did in your post here?

I guess I am saying that I can see the risks as well as anyone, and if this was before the fact it would be easy to tell Xtree not to get involved in this situation. But now that she is, it's not so easy to figure out what to do about it.
