What is the solution for dealing with a cousin who practices sodomy and attempts assault, knowing that he is 27 years old and the questioner is 20, and an attempted assault occurred during a family visit, and the cousin continues to communicate and harass via phone?

Sodomy is a major sin among the grave sins. One must be wary of its perpetrator, and he can be threatened with informing his family so that he may desist. It is not permissible to completely boycott the grandmother and the maternal uncle. However, there is no harm in refraining from visiting them if harm is feared, while being keen to maintain ties with them through phone calls and similar means.
