"I think it was an illusion because she was caught up in it and then realized I wasn't what she wanted."
Yep, that'll happen. :/ I would've fallen into much the same trap she did if my gf and her husband hadn't already been through one failed unicorn experiment, which taught them not to try to push things in that direction. It would've exploded in a different way, due to his lack of interest in me rather than my lack of interest in her, but it could've been just as unfortunate. It sucks when we have to learn things the hard way.
Me, 30ish bi female, been doing solo poly for roughly 5 years. Gia, Clay, and Pike, my partners. Davis, ex/friend/"it's complicated." Eric, Gia's husband. Bee, Gia and Eric's toddler.
