Requesting a divorce from one's husband

My husband is interested in other women. He stares at other women and he has told me that he cannot stop his eyes by staring at other women. He talks to every renter i.e. women. He makes other women sit on his bike by telling silly reasons and he even took pictures of our servant on his mobile. He texts awkward messeges to facebook girlfreinds. I made many duas in order to take him on the right path but his behaviour is not changing. Now I'm fed up with him and I cannot bear him anymore. My in law's also never take care about me. I wanted to take divorce, is it permissible?
