My wife asking to get divorsed with out proper reason

I'm from Hyderabad
I got married last 2 yrs ago in December month
on first night my wife said she don't like me this made me very panic
after 5months my father in-law came to know & my wife said as a childish mentality she said & asked to excuse me...I said OK
I was staying near to my father in-law house as my mother in-law is a patient my wife used to go every day
she never called even to ask about my welfare she used to stay in her house for 10 to 15 days with out intimating me
no call nothing some times I used to call her and ask her y ur doing like this & no answer from her side
I thought as iam near her house she z doing all these things & shifted to near by place
after one month she came to my new house & started quarrelling with me
again the same process shez doing and going to her house
one day she called me & starting arguing on all unnecessary matters
mean while my father in-law started torturing me to go for medical test
as this issue came to my Elders notice my family members and father in-law came to a conclusion to go for medical test after 2 months
my wife will be staying with me for 2 months for matital relationship
but
again my wife left my home in 6 days and started demanding for medical test
finally I went to a doctor with my parents doctor advised for counseling inspite my father in-law did not obey & called a rowdy sheeter & threatened my family
after 10 days I went & gone through medical test & got result POSITIVE with out any complications
after a week my family members went to my in-laws house to bring my wife
& my wife is not willing to come now
several time I personally went to meet my wife but their attitude is very rude and they are threating me
only our quarrels are on phone
I love my wife very much my father in-law working is going to retire in next month he is a central government employee
I don't want to loose my wife
every day iam suffering a lot...
how can I bring my wife & live a happy life..
