I lost everything in my life

I completed my masters and recently get married software engineer. As it is arranged marriage i don't know more about my husband and they didn't give us more time for marriage arrangements,all this done with in 15 days. with in one month i came to know that he has girlfriend science 2002 and they lived together in one house for 6 months they want to marry each other but i don't know the reason they separated.His parents also know all this, they deceived me and my parents. How can a girl feel after knowing all this, a women thinks that his husband is everything for her.He is 7 years older than me.I am not in a position to handle anything. I didn't tell this matter to any one. I knew all this by reading his dairy and phone conversations.Almost this is second marriage to him. I have one sister completed B.Tech,one brother i am the elder daughter to my parents, i brought up in very loving and caring environment but here situation is reverse he always likes to criticize me, quarrel with me for no reason.He always complaints about me to his mother and relatives. He is just like a psycho different mentality.They wants me to get a job but they are not ready to spend even one rupee for me.In college days i got many marriage proposals i rejected all those for my parents and society but finally i got this stupid dead life.Now what this society can do for me, nothing.I want to die but i am thinking about my parents. I lost every thing. i hope any one can give me better suggestion or solution to me,life long i can't live with this person.
