<human>: So, this girl and I got quite the history together. We had kind of an informal relationship three years ago; it lasted about half a year and ended before it could evolve into a real relationship because I had trouble committing myself to it – I had just come out of another relationship and was facing quite a lot of changes in my life. This lead to us ending things altogether and having a huge fight with a lot of bad blood between us. 

After we found back together a few months later, we developed a Friends With Benefits relationship for about a year, before I headed into a new long-term relationship – which did hurt her quite a lot more than I expected it to – but she got into one a few months later, too. 
Since then, we continued our friendship purely non-physically, mostly by texting and occasional phonecalls, and it grew deeper and more important to me than even during our 'relationship', and I really don't want to lose that ever again. 

I have been single for a year now, and about a month ago she broke up with her boyfriend, too. We see each other regularly (but not too often, as we live in different states now), and I feel like there could be more between us. 
However, she stated a few days ago, when we talked about "why we didn't work out", that her feelings now are **"still too much to go back to FWB, but too little for more than that"** since I've hurt her in the past and she doesn't want that to happen to her again. 

I understand that, but am seriously confused both by my own growing romantic feelings for her and by her statements – she clearly does have feelings for me, and we are definitely physically attracted to each other (we know that for sure), yet there doesn't seem to be a way for us to be together, apart from continuing our friendship and pretending our mutual feelings didn't exist – which doesn't seem healthy at all.

I just don't know how to progress here. Any advice would be very welcome.

Summarize the given text in a few sentences.
<bot>: On-off, but never steady, relationship with girl since three years, mutual feelings but she's afraid of getting hurt again, so says we can't be more than friends?
