Personally, I don't think blurred boundaries are beneficial in therapy, and I think that it can eventually end badly. How do you feel about her self disclosure? When she gave you a present on your bd, did you feel you'd need to give her one on hers? I think it's strange that a t would do that, btw, especially so early on. Idk. We are all different in what we like, need, want in therapy, so although this kind of rel'ship would never work for me, it might work for someone else, so just go with your gut on this one.
