I have some attachment and transference both with my T and marriage counselor. With T, it's some maternal T and a bit of attachment, but manageable, and we've talked about it. We seem to have become closer as a result.

With MC, it's more complicated, because he's male, there's both erotic and some paternal transference, and, well, he's my marriage counselor. I discussed it with him in a couple individual sessions. After the first, he seemed reluctant to do a second individual session (for various reasons--marriage counseling, plus my T is in the same practice, so he didn't want to interfere with our therapy, plus personal boundary stuff, I think). I became rather despondent (OK, I totally melted down, leaving him a sobbing voicemail), thinking he was rejecting me, etc. He called and apologized profusely, then set up another individual appointment and at the end assured me that his door is always open and that attachment doesn't necessarily mean seeing someone all the time (though I do see him regularly for marriage counseling), but just knowing they're there if you need them. I found that to be incredibly reassuring.

Not sure how helpful that is, but there's my experience. Feel free to ask any questions.
