Hi, I have been in a relationship with my cousin for 8 years, we were intimate and consensual. she used to harass me and blackmail me that if I don't meet her she will go with other guys, if I don't come with her for intimation, she would say that she would go with other guys. we have been intimate. The entire 8 years went along like that. also, she used to blackmail me that she will go with her past boyfriends, and when in a relationship with me she used to call one of her past boyfriends and trouble me. throughout the relationship, her parents have been filing complaints against me. I was mentally pressured to agree with whatever she used to say. she asked me to put a WhatsApp picture of both of our status, she asked me to put messages to her parents and i did I did and she even asked me to call her relatives to admit to our relationship i did. and i wanted to end this relatinoship. if i try to say she used to say she will put rape case, her family also said that and i tried to her parents as well. always she speaks me with vulgar words, she doesnt respect me. now 2 years back we are married, i don't wanted to marry before she was hitting me on roads to marry which I was not ready, she threatened to destroy my family and i agreed to marry. we went ahead and got married and were staying in our respective homes ( since 2 years she is in her parents home, after marriage, its been more than 2 years, we are not meeting for entire day and not intimate, we do meet couple of times in week some where no the way, but in a day half an hour or one hour we meet. she said me talaq each and every day after marriage, she went into relationship wit many people. she said she got married to some other guy and she said that she is confirmed. i do have these recordings, and she sent some snaps with some guys saying that she is married. some property litigation started, where we had rights in the property, now they have approached the police officer given another complaint to stop property proceeding and deviating, i am bit helpless, now her parents have put the case of exploitation against me and my dad. it is with the police, and I am not getting information. they are threatening me and worried about this threatens. what do I do? there is property litigation going on, they are indirectly asking us to forfeit the part. i am stuck don't know where to proceed, literally helpless,
