Husband wants me to see therapist

My husband has been pushing therapy on me for a long time. We live in Canada together and I am officially a Canadian citizen. I lived in America before Canada but I was born in Iran. I have not been to in Iran for 19 years. I suffered abuse from my husband when in Iran, I was raped... I watched my brother get publicly executed for lying with another man. Since I left I have done everything to forget there. To forget my home. My home is with my husband. I can get free therapy and my husband keeps wanting me to see a therapist. But I don't understand. Therapist won't make me unbeaten. Therapist won't make me unraped. Therapist won't bring my brother back from the dead. I will forever have been beaten, raped. The image of my brothers head will always be there. All I've been able to do is forget everything. Including my brother and move on. But my husband keeps pushing. What will a therapist do for me?
