Some general details first:
We've been together three years.
I'm 6 years older than her.
We met through mutual friends and live together.
Over the course of the beginning of our relationship I found out some troubling history on her part, of which was mostly not recent. I will try to make a cursory summary of some key points.
Her father sexually abused her sister of whom is 6 years older than her. Her parents divorced shortly after her father was incarcerated for other reasons.
Her mother later had a long term friendship with a "family friend" who was later regarded as my girlfriend's "godfather." He had lots of money and would take my girlfriend on trips, oftentimes just the two of them. He offered to pay for her college and gave her money and dined her etc. He also had lots of pictures of her. The "godfather" eventually asked my girlfriend about her sexual encounters with other females her age (she is and was bisexual), into middle and high school years. This later turned into a series of sexual advances of which she claims were never acted upon and while "disturbing," she continued accepting means of financial support from him (that could be considered "hush money") while he continued making remarks and advances sexual in nature. She would also visit him and he'd also leave pornographic material out when she was younger. Later he also bought her a car if she agreed to have sex in his van and at a hotel, but she said he changed his mind at the last second and bought her the car anyway. Up to the point we started spending time together she would still agree to have lunch with him on her lunch breaks and he'd give her some extra money. Upon my knowledge of this and seeing my problem with it, she terminated her relationship with him. To my knowledge her mother only knew about the money at this point.
Now the second thing. In my girlfriend's high school years, her mother became close friends with a neighbor family. The mother in that family has always been a drug addict and my girlfriend would act as the son's and daughter's "caretaker." One night she was staying overnight at their house, the father requested her to come to the garage while the rest of the family was asleep (I think). He offered her cannabis and she smoked it before he made sexual advances on her. Eventually she "panicked" and ran out to the son's/daughter's room where she felt safe and stayed there the rest of the night. My girlfriend says her mother didn't believe her later on, probably in part that my girlfriend at the time was also very sexually curious and was caught chatting online in deeply sexual, alternative roleplaying games websites. This was all around the age of 13-14. Later the father was arrested for molesting his own daughter. To this day my girlfriend has a very strong emotional bond with the son in that family (who is now 16 yrs old, she is 26).
Now the third. There was another family friend/neighbor to my girlfriend's mother in her high school years. Later the man's wife had killed herself in front of their own child, [I believe] on suspicion that her husband (the family friend) had some kind of feelings for another female (not sure who). But my girlfriend claimed it all felt like a dream and was confused I guess. Later, she said that one night her mother, while inside the house, asked my girlfriend to give this man some [solace] while he was tending to his docked boat. Needless to say it turned into another sexual advance of which she claims nothing happened. To this day that man is a neighbor and has been in a relationship with another woman of whom we were all friends with up until we moved in our first year in a romantic relationship.
This is only a brief summary and I'm sure I left some details out, however I will do my best to recollect them and add later.
I also found a sexual video on her phone a couple of years ago. I refused to believe it was her sister as she claimed, and she finally admitted it was her and a guy friend she was still in touch with (in another state). She said she forgot she still had the video.
Other than this our relationship has been relatively steady and mutually beneficial.
I just don't know what to make of all of it even to this day.
Thank you for reading.
