The unsuitable & unavailable may actually be part of the draw. And, I'm not saying you weren't demonstrative and that she went to OM because of that. She knew you found her attractive, but that was because you loved her. OM found her attractive wo/ already having that bond. That was the new affirmation. The conquest of still being able to reel someone in that isn't already attached. It also had that he has a thing for me despite it being inappropriate. If he isn't really available for a long term thing right now, that can get read as I'm such a desirable woman that he can't help himself despite the inappropriateness and availability. See the draw there? There is nothing you could have done to avoid that. Nothing. This is about her needs and desires, about her unresolved issues and insecurities.
Sure, the M had problems (which you know) and you still may have ended up in the S & facing a D. But the A part is all her.
Hang in there.
