She "sorta" cheated on her boyfriend with a girl and apparently I'm "sort of responsible"

(Should've probably asked about this before asking for book recommendations. Anyway... KINDA LONG STORY, NEEDS PATIENCE TO READ)

So, Lady at work has a boyfriend, they've been together for years apparently.

Lady at work found out I like both men and women.

She asked me a bunch of self discovering questions. Pretty sure she was bicurious at that point so I told her how I learned about my sexuality and how I came to terms with it (Eldest daughter of an Asian household does not a very acceptable environment make) and dealt with family and society and all that. She said she's always thought of her self as straight and thanked me for sharing my story and then we went about our days working as corporate slaves.

AND THEN

I found out her and another coworker were being very sus and it turns out they've sort of been um... "exploring a new found friendship" by ways of less than platonic activities. Apparently, if they didn't label it, it doesn't count as cheating. Her boyfriend found out though and things went sideways. More than sideways, considering her sexuality also left the "straight as an arrow" path.

ANYWAY

She went "if you hadn't told me all those stuff, things wouldn't have gone this way".

SO MY QUESTION IS, HOW SHALL I DEAL WITH THIS? Shower me with some wisdom please. Thank you.

She's being ridiculous. She also sounds like a cheater. She got found out and can't take the heat, so she tried to blame you. You had nothing to do with it.

@uncalled4 Thank you! But how do I tell her that without seeming/sounding like I want to give her a huge middle finger salute? Because I very much want to keep it mature considering our group dynamic at work is suffering.

@DeletedReality You don't. You're not going to reach her. She's a co-worker, so just talk about work.
