Married due to family pressure. Can't take this anymore. Need divorce

I married my first cousin last year as my parents and her parents put a lot of pressure. I had to succumb. She's good, but to me she's dumb. She's not smart. Since I don't love her, I never made love with her. I'm getting frustrated day after day and begin worrying how my aspirational life became a senseless useless one. All the relatives and parents who forced me to this marriage are behaving without empathy on my side and are supporting her. We still stay together, as I'm afraid of my family traditions. I really need to get out of this without much harm to her. Pls advice.
