Well, you were right.
We had "the talk" tonight. She just asked me: "So...what exactly is this between us?".
I told her that I still wouldn't say no to a relationship (which I told her a month ago already).
She said that she's a bit scared to fall back into some kind of weird behaviour, but she wants to work on it. I didn't ask how exactly this behaviour would manifest itself (I didn't want to ruin the moment, as I knew it has something to do with her ex) and simply said: "I'd be happy to help you with that."
Her response: "Me too."
