Divorce by Mutual Consent

I was manipulated by a guy wherein he forced me to marry him. Though i was against this marriage i don't know what went wrong and finally i did accept. Later on i came to know that his educational qualifications are very less whereas i stand from a background with masters. The day we married, i came back home and never went away with him. Now he says that I forced him for marriage and he says he has proof for it. I accept that i was around him without my parents' knowledge about this. He has photographs to prove this. But all those photos are like just sitting beside each other. He comes home and threatens my parents but i have no proof for it. All i ask him to do is stay away from me but he calls me over phone every now and then. I'm against this act of his' and want a divorce based on mutual consent. We married based on registry. I'm from West Bengal and he belongs to Karnataka. It's been 5 months since we got married, can i apply for divorce now? Or should i wait for an year to apply for it? What are the procedures that i have to undergo?
