Friend grew up with swinger parents. Now she is a who is screwing me a man. what do u think?

About 4 months ago I met a really nice and attractive girl. I ignored what she was saying because my little head was thinking. The girl is a hour gl shaped redhead. I was blown away by how attractive she was and still is. WELL, she told me she was married to a russian guy who is gay, she lives with her girlfriend and that she wanted to have an affair with me. She told me she married the dude so he could become a US citizen and so she could use his good insurance at his job. All of this was real weird to me but I begun having an affair with her anyway. WELL, she begun to tell me about her upbringing. First, her parents are drug head, alcoholic bikers and always have been. She grew up in a house with her 8 sibling and about 5 other people and parents. The icing on the cake is what I found out this last past week. She didn't tell me but I found out her parents are and have always been swingers. her mother works at the same place with us with her girlfriend who lives with her parents. So this lady dates her mom and her dad. I had been so confused about why this young lady was so confused. NOW I know and even though she is nice. I really don't like her at all. I feel so grossed out because I had with her now. I guess my question to you is is she messed up and confused because of her crazy parents?
