Is my life at risk? I am hiv positive and taking treatment but my husband is hiv negative he is blood type O. he doesnt want us to use protection. What must I do?

Depends on treatment. Whether your life is at risk from HIV depends on whether you are on treatment and tests for the amount of virus in your blood (viral load) and immune status (CD4 count). If you're taking anti-HIV drugs with good control (undetectable or very low viral load), probably you will live a long life and your husband is at little or no risk, even without condoms. His blood type makes no difference.
