Perhaps she could have explained it better. But also you say your husband met with her alone, and then he told you what she said? Maybe that's not exactly the way she said it. Remember the childhood game of "Playing Telephone"? The 2nd person never relays the story the way the first person said it. And if your husband has mental health issues, he may have more trouble sorting out what she said - it's possible you'd have heard something different.
It may also be that your husband communicated, in these 10 minutes, such a massive array of issues and perhaps his own demands about someone's experience and credentials, that she picked up on his unwillingness to fully participate in therapy? Or perhaps she felt there would be medical issues involved and that it would be more beneficial to put some or all of you with a clinician (psychiatrist or at least a multi-person practice) who could prescribe medication if needed.
If you went to your primary care physician, described your symptoms, and that physician referred you to a specialist, would you be offended that this wasn't your physician's area of expertise? Or would you say you were glad the doctor was referring you to someone with the appropriate focused practice in the subject area? You'd probably appreciate it. It works the same way with therapy. They have specialties, areas where they focus, and so on. They also have existing client loads and may feel that they don't have enough openings to help several members of one family without you having to wait for appointments.
It may also be that your husband, because of his personality or perhaps bipolar disorder (if he's been diagnosed) gave an indication that he's not all that open to therapy anyway, or that he's not really feeling a connection with her at all. In which case, she would spend the first few months trying to convince him to participate, to trust her, to respect her, and so on. He's making decisions about other therapists without even meeting them, right? He's looking at their resume or where they went to school or what they list as their areas of specialization, and making decisions before the fact.
So I would go back to your prior therapist for a referral, or go to your family physician who already knows the issues in the family, and ask for some referrals to a practice that takes your insurance and specializes in the initial areas of need in your family. It may be that there are other things that will be uncovered and prioritized during assessment. Sometimes what WE think are our biggest problems just aren't, because there is an underlying issue.
It's really important that you not take this as an insult, but as a redirection toward someone who can help you. There is always help out there - so why spin your wheels with the wrong specialty? This is NOT a situation where the problems aren't fixable! So if your husband is discouraged, then you have to be the one to find a new person. Someone who has experience in dealing with clients who don't like a lot of therapists and who prejudge (or judge quickly) whether they are going to be "acceptable" or "qualified" is what you want.
In most cases, it IS helpful for each family member to have their own therapist so they feel that their own issues are front and center (as well as confidential). My husband and I did that - we each found someone in a group practice who would then (and only with our permission) speak to each other and help come up with a combined approach. We had our own person, and then we worked with one of them with both of us in the room. It worked out great.
