She is monogamous, but ok with opening relationship(Which makes sense considering how she was raised and lived her life pre Tav). Thats how I read it.
Then we only disagree on the type of poly we see. Please the read the article I posted - you just described 'mongomish' which is a type of ENM
I've checked your article, dont worry. She falls under "monogomish" descripion yes, only if you consider Halsin as not a fling. If you do however, she is basically "open monogamy". And sorry, I haven't intented to be mean or anything btw.
