Ex-FWB is really starting to bother me trying to stay 'friends', how should I go about fixing this?

Long story short this girl and I were friends with benefits up until early November. She broke things off because she was worried I was getting too attached (I was) and that I was going to end up hurt (too late for that). She insisted she wanted to be just friends. We'd only hooked up starting in late September, but considering that we spent literally almost every day and night of October together I did get attached.

So while we were 'just friends' having her message me to hang out or play games through phone apps did not help the 'getting over her' process. What ESPECIALLY didn't help was when I came back from thanksgiving, Tuesday night she tried to get me to hook up with her again. That lead to a week's worth of fun where I had to ask her why she did that after insisting we were 'just friends'. Evidently she thought I'd be over her by then and we could go back to the way things were, she apologized for leading me on. She asked if I still wanted to date her, I told her yes, she said it was best if we just stayed friends then.

Not TWO DAYS after that she's messaging me now at 1:30am saying she has pizza and if I want company I can come over. I asked back 'the company would be nice but aren't we just friends now?' and her response was 'we are just friends so we can hang out'. Note that the night she tried to hook up with me last week all that had happened is we cuddled in her bed and she had wrapped herself as tightly around me as she ever had telling me how much she'd missed me (leading to more feelings of attachment).

I'm getting extremely frustrated with her. She legitimately cares about me, I know that... but this is really starting to mess with me. Best to just cut off all ties with her?
