Prohibited Relationships

Dearest Rabbi, I am at the "end of my wits." My own mother's sister raped me when I was all of four years of age and again at fourteen years of age. How do I "even" deal with "this..?" "This" being incest and in my own family. I am struggling mightily day by day to "cope" with the devastation and the long term consequences (sequelae in psychological "jargon"). I am fifty-eight years of age and I have not to date had one single relationship romantic, dating, anything at all.

A few years before I was born, my mother had an adulterous affair and got pregnant. My father knew about it and was angry at first, but then he forgave my mother and remained married to her and raised my brother as his own child. My parents kept secret from us for many years that this happened and hid the fact that my older brother is not my full brother. Only after my brother and I grew up did we learn the truth. Presumably a child born from adultery is a mamzer, which would make my brother a mamzer. But I also understand that once a woman has been unfaithful to her husband, she is forbidden to him and they must divorce. Well, my parents did not divorce and have married to each other for almost forty years. My question is, since my mother was already forbidden to my father at the time of my conception, and he knew that but remained in his marriage to her, does that make me a mamzer?

So rabbi, some feminists says the Torah prohibits adultery. But all females must have the right to do adultery. Moreover those females who commit adultery never confess that they committed adultery. Now, does what the oral law of Judaism say about adultery?

Do you think that the collaboration between Islam, Christianity, and Judaism can prevent adultery from happening anymore? If so, please explain how.
