My first therapy was couples therapy. I grew to really respect the therepist and finally got up the courage to ask to see her individually too. Sometimes I do think it would be better to have a different therapist for my individual and marriage counseling, but the thought of starting over with someone else is too hard for me. It takes me a long time to open up and I'm not ready to do that again.

I would say, that as long as the therapist is a good one, there should be no problem with them being impartial and able to separate the couples therapy with things you tell them individually. That has never been a problem and my therapist asks me every couple session if it is still working for her to do both.
