Seeing the same therapist as your significant other?

Are you in the US? Perhaps it was just my T and not an actual rule but she refused to see me and my partner separately. She said it would be a conflict of interest thus she wouldn't be able to effectively work with either one of us. There's a term for it that I'm blanking on.

i see the same therapist as my husband sometime we do couple therapy and sometime individual.

That sounds like a huge conflict of interest. The only time she has seen hubby is when he has come to my appointment. T recommended it but said I was the one in control of whether he comes or not. She will not see any family members. Shortly after I started seeing her she asked to hubby had any siblings who might be looking for a T. A couple with my last name had been referred to her and she wanted to make sure it wasn't a family member. I told her my in laws names and a bit but said I doubted it was them. She said if it were a family member she had other T's she would refer them to. About a month later I saw my Brother in law and his wife seeing another counselor in the building...

The craziest therapist I ever saw would see clients and their friends and their family and spouses/lovers/partners individually and together. She claimed to be the only qualified therapist in my area (a largish metropolitan area) who could handle such matters. I quit seeing that one quite quickly.

This would be a huge trust violation for me. I really don't know if I would be able to stay with a T who did something like that. I don't think he ever should have agreed to see your H. He could have made referrals on the phone or something. But I just don't think that this is right under any circumstances, and it raises serious questions in my mind about the quality of a T who does things like that. If your T doesn't change the situation immediately you may have to tell him that you have to leave. I just don't see how you could trust T to really keep it separate.
