@Sumita, your actions do not reflect your philosophy. You have filed a DV case and you expect to amicably resolve your problems with your husband? These two are mutually exclusive. Right to residence can be filed through a civil case rather than resorting to a quasi-criminal case (DV) which can only exacerbate the strain in the relationship. If he suffers from impotence, I see no way your relationship is going to work out in the long run.
Either way, rather than going through a "tough journey" with "truth on your side," just file for divorce and move on. Fighting in Indian courts will adversely impact you mentally, financially and emotionally. It does not matter on whose side the Court finally rules, both parties are losers in legal matrimonial disputes. So, if you are philosophically inclined, practically oriented and optimistic about life in general, then the best approach is to severe ties, forget about maintenance, ask for divorce which he will surely give without alimony/maintenance demands. Then find a new man, get married, have kids, etc. For women, age is of essence when it comes to second marriage. Filing for RCR will dilute the impotence basis for seeking divorce and only delay the ultimate outcome which is clearly going to be divorce, anyway.
Pause for a day or two and think about this approach... Seriously.
