Can I apply for Divorce on the ground of Cruelty

I got married 7 years ago. We have a baby (girl) in the the first year of marriage now she is 7 years old. My wife doesn't not allowed me to have sex with her (except 4 or 5 times out of 7 years), she was not preparing food properly and timely, she regularly (at least twice in a year) leaving our house without informing me and she will go to her mother's house, she used to black mail me (over phone), with all these circumstances I shown very much patience becoz I loved her very much. I have old parents, when our family got devided an understanding between our brothers is that we need to taken care of our parents by six months each (the division happened before my marriage). After marriage when my time comes to looking after my parents my wife doesn't allowing my parents to stay with us and she will leave my house without intimation and when I ask her to come and join with the family she always used to put a condition that, I will not stay with you when your parents come to us this same situation got happened many times. Six months back again she left my house without informing me and when I was at my office and putting same condion that she will not looking after my parents. You please advice what course of action I need to take. Note : I don't have any bad habits and I can prove my innocence. Please help me...
