I want a divorce

Last year september i got married to a girl from my same village. initiall everything went well for first 20 days. she wanted to pursue her higher education so i paid her college fees everything. my parents deposited the gift amount in her name. being a only child we took no dowry. one day her mother called her and told her that after going to a rich family you have forgotten us and both stated crying. i asked the girl to go and visit her house and come. she went and stayed there for a week and came back. after 25 days she complaint of ill health, i told her that i will take her to hospital in the evening. when i came back my parents informed me that her mother took her to hospital and she is in their house.things went in the same way.. finally before Christmas she asked me to drop me i her house. i did it after that she refused to come back. she asked me to abandon my parents and stay near their parents house. i told i will never do that as they don't have nobody else except me. 10 months have passed i called her three times to come she didn't replied to that. now her family groups are compelling me to go to their family. but i don't want to do it. rather i want a divorce from her. what i should do
