This therapist might be an excellent couples counselor, but not have experience with mental disorders, which could be why she didn't address it. One of the things you might want to consider is to find a therapist who has a lot of experience with BP, particularly if you are trying to manage without meds.. I've been to both kinds of therapists and I can say for certain that the treatments are completely different. And I think it's likely that if you are in therapy for BP, it will help your relationship.
