Call the police, report him. Being silent about this won’t do any good either to you or his family. They need him yes, that’s why they need to know about this so they can see his true face and not just the mask he’s putting on. If you truly care about your aunt and cousin, then let them see the real him. Who knows how many nieces he has raped? If you can’t do this for yourself then please do this for the sake of his family. Simple logic, if you were your aunt would you want your innocent niece that you love dearly to be silent and carry the burden alone when your husband raped them? Report him so he knows he can’t get away with this just like that. Report him so he won’t do it again to you. Report him so there won’t be any other victims. Please love yourself
