is she really desperate to get away from me because shes afraid ill take him?should i just let her be silly and stop being 프렌즈 with her?what should i do?

last week i was babysitting for my bffs little brother and sister and she came 집 with her boyfriend. he was really friendly with me and im sure shes got the impression he was flirting with me. ever since shes been trying to avoid me and is giving me looks and is hanging around with a girl she knows doesnt like her. is she really desperate to get away from me because shes afraid ill take him? i never would and she knows that. should i just let her be silly and stop being 프렌즈 with her? i dont want to lose her but i cant be bothered with her recent attitude. what should i do?
