want divorce after 9 years of marriage

I am a woman and am married since last 9 years. I have two daughters - 6.5 yrs old and another is just 3 months. I have problems with my husband since I got married. As he is very short tempered and always doubtful about me without any reason because of which I am not allowed to do anything alone. I thought time might solve my problems but it did not. Please advice me what is the best procedure for divorce and how to proceed it. I am ready to take both my daughters responsibility. Please advise me.
