Hi... Please first get her assessment done from a Psychiatrist/Clinical Psychologist. You need to know exactly what she is going through.
Counselling takes place in a confidential environment. So may be that's why the counsellor is not involving you in her treatment. But with clients informed consent, the counsellor can share a brief about her condition and treatment.
If the frequency and intensity of her suicidal urges is high, please don't hesitate to take a Psychiatric Consultation/ Medication, as it is sometimes necessary to prevent a negative consequence.
