I find myself inconclusive about her type. The one thing I'm sure of is that she's sensing and rational. No intuition whatsoever..
For the most part, we don't get along.. I suspected her to be ESI, LSE and any other sensing type but those two are my main candidates, with LSI as a plausible option. The thing is that I'm not sure if she actually values Te/Fi. At some point I thought she was Fe seeking but my reasons were quite shallow.. She loves smiley people who are warm and inviting and dislikes atmospheres that are not visibly happy and cheerful. Those were my main reasons for thinking she's Ti/Fe.
I always thought she was Gamma because I could easily see her as having extraverted sensing as a creative function and she tends to be very morally preachy.. very. And really critical of everything, from aesthetics to lack of morality in other people's actions. I made her take socionics tests and MBTI test and she comes out as ST.. But I always get a strong judgmental vibe from her as far as critiquing if others are tactful and cordial, she loves people who have great social skills and critiques those who might be awkward in social settings and don't quite know how to behave and what to say, it's a real turn off for her. I'm much less judgmental towards these things because to me it seems unfair to judge a person on how well they handle a social situation, it doesn't matter to me at all as long as they are respectful.
She's very strong willed and persistent in everything she does. She wants a partner who will take care of her when she's sick but insists that she doesn't want a dorky guy. She likes to present herself as a cool groovy person, when all I see in her is a judgmental witch..
So, this was partly me ranting but if you have any questions feel free to ask
