I have gone through your matter, it is great that your cousin is tolerating since last more than 7 years. Ony end of relations i.e. divorce is not the solution of the problem, You try to get together both of relatives & your cousin will put her problem before them , there are chances of solution & settlement. So you firstly try the same then after if not any solution she may move before the court of law for maintenance & also for criminal prosecution against culprits for cruelty & other. This forum is against injustice & corruption, so we will co-operate , no neeed to worry.
