hi rhea,
after going through your case you have said in one of your post - "they are not willing to let me resign and find job and delhi and stay with the guy ." interesting point here is groom family nor groom interested in you.
another point - "They want me to keep working and visit their home occassionally and the guy is not willing to take responsibility." here your husband & there family want to continue your work at your home town.
next point - "This marriage involved huge amount of dowry which I dint want but they gave for the name of society" your family already given huge amount of money and other belongings to groom family.
last point - "Before marriage only I had told him everthing about myself. I never has any relation still he doubts me, he himself had girlfriend to whom his parents dint approve of." here your husband have girlfriend and make sure whether you have got any similar kind of relationships are not.
from going through with your complete posts, your husband family got huge amount and they want you to be money making machine, where as they want his son to continue his relationship with his girlfriend. please take "Anil Upadhyay" advise to make sure you have made last attempt to save this marriage, if you can't or if it unsuccessful then please continue your life with your parents. Even if they are bothering you then start independent life by filing MCD, God Bless You!
