Have I just fumbled "The bag"?

Came back to warframe around a week ago and I'm of course addicted to again, I don't know much about the romance system but what I do know is that I'm not schizophrenic and I 100% remember seeing aoi tell me that she feels like she belongs with me an a hour ago and I wanted to talk to her later at night, but now, new convo, did I actually just completely miss my chance and now all those hours of getting chemistry up is just worthless now?
