Not sure what to do about this girl

Me and this girl are extremely close (physically as well). She ended a relationship at the start of the year and we have been friends for 3 years. We meet up every fortnightly and we send each other x's at the end of the messages and share very personal information with each other. However she has stated she doesn't want a relationship at the moment and not sure if she wants one, but she us messaging a guy also sending x's to each other. They haven't met and tells me things he says to her. He asked to meet up with her and she said told me she won't meet up with him for at least another month, I have asked her about him and she says she only wants to be friends with him. But it's clear he wants more than that, so I've told her that. But when I mention it she gets defensive and says she won't get with him. But she knows his intentions and she has messaged him at one point saying if he misses her. (This one when she was with me in person), I'd like to also point out she asked me to put my fingerprint on her phone so I can unlock it which I did. So it's mixed signals it feels like and not sure what to do, she knows I like her romantically and we do go on meals and trips away. Just confused about it all
