my boyfriend accidentally called my best friend babe

he was drunk and we were all in his room and he was looking at me as he was talking to her, so he slipped up and called her babe. he realised straight away and said “omg i’m so sorry i was looking at you so i slipped up” but i looked at my friend and she was grinning from ear to ear. maybe because she found it funny, but the thing is she revolves around male validation, and i cannot put that lightly enough i’ve never met anyone as bad as her in that department. but unfortunately no guy wants her so i feel she really was gloating when he slipped up and said that. she also mentioned to my other friend rianne that my boyfriend had said that to her so why was that noteworthy enough to mention ew
