Suffering From Anger And Suicidal Tendencies. Having Troubled Marriage. Suggestions

Hello, I am getting anger over & over and teh sucidal tendancies are growing; my wife has a abusive nature, which can neither be seen by anyone or be proved its only me the victim who suffer. I am from Indian orthodox family which is making me suffer more; she is pregnant now an making use of more sultry ways to let me down the same with my in-laws the final thing she needs is i need to become a puppet like a doll and lot many things, even i bet i did not make love with the feeling but it was a duty i had to perform. I am suffering more & more & more. I am worried wat am doing please let me out, I want to run away from the relation but this should not be the solution, I want to end my life again not a solution. Its being 2 yrs i got married I lost control on my life since then i had to quit jobs because for her abusive nature, my career graph came down; I tried to expalin my parents and family but they say watever we dont want the family name to be ruined which means wait till she changes or live as it is. I am worried I goinf insane day by day
