My maternal family was relatively wealthy in the past, and my mother has a domineering personality. She always wanted to have the final say in family matters, which eventually led to my parents' divorce 23 years ago. My mother now lives alone, and my siblings and I have never visited her. I harbor deep hatred towards my mother.

I have been married for 9 years now. My relationship with my wife's brother is not good, and I constantly feel that my wife is not loyal enough to me. I strongly wish that my wife would let her younger sister have sex with me once, only then would I feel at ease. I've brought this up to my wife many times, but she refuses to agree.
