Then you need to move. The fact that you have any expectation of continuing to live in an apartment on her fathers dime absolutely blows my mind. “I was just going to bring it up,” and it’s an insanely stupid thing to bring up.

She’s been paying (her portion of?) rent for two months while gone, that’s not a small amount of money. Even if you were going to try to corner her into staying at her boyfriends or moving out; that is a super shitty thing to do to anyone. Even someone you don’t consider a friend anymore.

Start apartment hunting and get a reality check. It’s hard to believe this isn’t a troll because of the pure audacity.
