If he’s paying her tuition , does she have to be exclusive to him?

Was listening on the radio, a guy called in and said how he pays his gf tuition; and he was on her phone and there was several dating apps. And one serious conversation with some guy. The radio show hosts called the gf pretending to be the guy and .. lead her to a meet up.

The bf starts going off and the gf is unapologetic with the .. I told you I want to enjoy my college years doesn’t matter if you pay my tuition.. blah blah. Broke up with him

Then hanged up
