Called it long ago - she wouldn't do a thing until it looked like she'd be left behind.
Wish it weren't so predictable, because having her be genuinely not interested in romance with him would have been very novel. This whole "I don't know or understand my feelings!" only to purposefully sideline him only to then get upset when it appears others have interest in him is just ....kind of exhausting.
I'd prefer she just make up her mind and stop lying to everyone and herself. She wants so badly to not hurt anybody, but all that's doing is screwing up the calculus for all parties involved, and the more she ran away from the truth the more pain it was going to cause.
So in that sense, at least, I'm glad to see things are finally starting to get underway.
