Facing one of my abusers

my childhood abuse changed who I was, it made me into who I am;
it took my innocence away, it made me unable to tell what was or was not acceptable.
I made many mistakes, many bad decisions, I had to learn as an adult, and I have.
I am no longer a victim, now I am even more that just a survivor:
I AM HEALTHY
Yes I survived, but that survival mode nearly killed me, it nearly took me away from this full, tough,crazy, life of mine. A life I built, once I exited survival mode, and entered my true life.
I do still struggle at times, like in the last few days, information was given to me, from a sister, who identified an abuser, he molested me at a very young age...I am going to speak to him and his wife for answers. I am not doing this in anger, it is more like investigating my past. I have many fractured memories, and all I hope to get are some more puzzle pieces to fill in gaps, put faces to faceless abusers, create a more defined time line.... I have so needed these...
I had so many "blackouts", yet some memories so very vivid and accurate.
I spoke to him on the phone, he sounds very confused, I heard that he is not doing well mentally, so my hopes are not too high about what he can recount to me. I hope his wife can be forthcoming...This abuse/incident, was supposedly reported to my mother, he is her brother. I have only faceless memories of a sexual nature, that are inappropriate, I was abused later in childhood too, by others...
I am not angry with him, it makes me sad that his two kids grew up without a father, that his first wife may have left him because of what he did to me, I know he once express great regret, and guilt, over the incedent: that in itself comforts me, even if I won't hear it when we meet. I am VERY angry at my mother, for not doing anything, did my father even know? what about other family? why did no one help me!!? My mother is a very unwell person, mental illness runs in the family, she had another brother who, supposedly (again) ended up commiting suicide, the night he planned on killing his ex-fiance and her parents, my maternal grandmother supposedly left her husband and 4 kids to run off with a taxi driver, she ended up in a mental hospital where they treated her to a labotomy, I think I saw her after that, but I am unsure, she died over 25 years ago... I need to research if and how I can my hands on her medical records....
All that to say, this is how I process things now, I need to know, I need to find the truths: having lived a lifetime of lies, and secrets.
During the early years of recovery, I was overly open with everyone, I had no blinds in my windows, like I desperately NEEDED to let in the light, let it be known, now I fully understand.
