Yes, this ESI is a puzzle. When I first saw about ten of her pictures on Match, I thought she was an SEI. But there were two pictures where she looked EII and one where she looked angry and slightly insane (ESI) and so I thought they all might add up to an ESI with a very disturbed upbringing. Her father looks SLI. Her mother saved money and might be EII.
When I first met her, her Si was through the roof. She was channeling my SLI-Te ex about 80% of the time, but when I talked to her about finance, her face melted into an attractive ESI's face, so I thought there might be hope.
I've since learned that her father is SLI, her brother is SLI, and her sister was mentally disturbed. She's also been married to an LSI with whom she had a competitive relationship, not a partnership. Her first husband was an SEE, and her son is an ILI, and she really dislikes her SLI brother's wife, who VI's as SEI.
Overall, I'm now pretty sure she's ESI, but @Rebelondeck, I agree with you. She seems to have a LOT of baggage. I don't think she's ever met an LIE before, and she's just really, really holding me at a distance.
Let me ask you this: What is it about her speech that makes you think she talks like an SXI? I know a few female SXI's, but my assessment of them is entirely through VI. I mean, my SLI ex's Si was mind-numbing, and this ESI has incredibly strong Si but she never talks at great length about how to chop vegetables, or how she color-coordinates her shoelaces with her eye color. (Just kill me now. Please, God, make it stop.)
Basically, I see visual differences best, but I'd like to know what you were seeing in her speech.
