Legal action to be taken if wife is not willing to come back home

Hi, I m from chennai. I just got married on 2018 julyt 1st. we were together not even for complete 15 days. later she went to her house for aadi month(as per tamil ritual couple will be seperated for a moth), now from their home they are saying she is not willing to come back, as she got tortured. she cries like any thing was the statement said by their homemates.Infact to say she got fainted more than 5 to 6 times in bed during intercourse, so i didnt try anything so far. so far nothig happened, she is still a virgin. i kept my patience stil alive. she is not willing for intercourse it seems, for which she is trying to avoid by balming on unhappened issues as happened, many lies. their home members believes her since she cries a lot saying TORTURE. just with her crying and and word TORTURE they want seperation now, she lags not only with the knowledge of what & who is husband but also sexual knowledge.she feels very awkward with name SEX itself. what has to be done. please advise.
