Really depends, tbh, something similiar happened to a cousin of mine (except it wasn’t intentional like OOP) he helped her get healthier and she overall looked nicer, she got so much confidence that decided to break up probably for someone that looked better or sum shit (he is a really nice guy and treated her well, so i doubt it’s because he was a piece of shit nor he told to us about anything that happened between them)

So yeah, depends on the person but most likely she wouldn’t depend on OOP too much because she now know how to stay healthy and she def know she isn’t that bad if she goes out alone
