21yo plate keeps going back and forth between "I really like you" and "I want to have fun my senior year and flirt with other guys." I said I'm cool with either decision and walked out her place. This has happened before, and every weekend she booty calls me at night. I'm so sick of hearing her hamster on about this shit. I told her I'm perfectly fine with seeing/fucking her and she can go flirt with other guys but she said she's not cool with that and considers that cheating (wtf?).

Is there a better way to go about this?
