You are living in a country where women are harassed from their birth. Even getting birth as a girl is becoming 'miracle', when the scrouge of female infanticide disease has become inate rampant character of the society and is eating the very veins of the society. Girls aged between 5 to the oldest women of 80 are being raped and the country has been noted as the most dangerous place in the whole world and proper cautions are being extended to the unwary visitors from abroad. Domestic violence and harassment at workplace has become norm and the judges to socalled saints are no exception to indulge in those activities. Every day on every street either it is urban or rural, women's modesty is outraged without impunity. If a woman has to get married she has to bring fat dowry and a very lucrative job so that she can be milked every month and also a free domestic worker to serve the 'old', 'sick' and 'aged' parents of the husband. You go on making laws for protecting the women but not execute them, then you will be in sorry state. The country is going through such pathetic and patriarchial stage and you are no exception. There are several women harassed by the husbands and in-laws physically, mentally and financially and filed the cases under Section 498-A without any bleak hope to get positive result.
If you have solid proof of your exploitation by your husband financially, physically and mentally(for this last offence there can be no physical evidence possible), you pursue the case. If you show that in your salary substantial part is going to your husband and also you show that substantial sum has been spent in marriage as dowry or gifts to husband and his relatives you can bring these facts before the court. If you have been physically beaten and for this if medical evidence is there, that is also well and good. If not if you disclosed this fact to any one of your near friends or relatives, they can come to the court to substantiate the veracity of your statement. Mental harassment can be proved by way of circumstantial evidence and also your statements on oath.
Regarding maintenance, as you are working you may not get. But your child is entitled to maintenance and for that you have to apply under S.125 cr.p.c. Further, after discussing with a good lawyer, you can file domestic violence case to realize compensation and/or maintenance.
wish you best of luck.
