Divorce

I am a 62 yrs old Christian woman. I married at the late age of 39 yrs. In the very first year of our husband I discovered through many known people, family friends, eye witnesses and even distant relatives of my husband that he is a drunkard and has many female friends, a couple of whom are characterless women. I have a daughter who was an infant and because of her I did not want my marriage to break in my early years of marriage. I tried my level best, both through stern warnings as well as affectionate ways to give up his waywardness but it was all in vain. He was holding a very senior position in a global company an was fooling me while I was busy bringing up my 'adopted baby'. The adoption was by mutual consent. I was working as a PG college lecturer when I got married. I gave up my government job to join my husband in his city. He was pending nights away from home and wasting money on women. When I questioned him, he said its his money not mine so he is free to spend the way he wants. I joined a prestigious university as Asst Prof but had to give up as my baby had health issues. For the last 22 yrs we have lived in the same house but separate rooms without any physical or emotional relationship. 15 yrs back he lost his job because of his waywardness. He has poor vision since childhood. Currently I am a freelance author and teacher trainer for publishing houses. After my regular job it is a struggle for me to make ends meet with freelance work and complete responsibility of the family on my shoulders. My daughter has completed graduation and is seeking admission in PG. I have been paying EMIs of my home loan even now. He only sits and drinks daily before lunch and dinner. I am now fed up. Since my daughter is mature now and she is seeing his habits I now want to end this namesake marriage. My husband is not on talking terms with his mother. They have their own house in which he and his sister have equal share. My present house for which most of the loan has been paid by me and I am still paying is a joint property of me and my husband. I want to have this property solely for the future of me and my daughter. My husband had once attacked me physically on questioning his whereabouts, over 15 yrs back. He had hit me on my eye and my vision was permanently damaged. For the treatment of my eye, an FIR was lodged in the local police station. I have been suffering everything all these years in the hope that things would change and more so for my child. But now I have given up. Pls suggest what to do to seek a quick divorce.
