One day me, my partner, my best friend, and my bestie's friend (who we'll call Alana) we're all sitting together and somehow the topic of weight came up. My partner is chubby. We both know that and we both love that, but Alana is very skinny. And so when my partner said their weight Alana made a comment along the lines of "Wow! You weigh ___ pounds??? You need to loose some weight!" And when it happened I knew what she said was bad, but I didn't know what to do, so I looked at my best friend. My bestie immediately stepped in and told Alana what she said was wrong and reassured my partner that they were fine. And after my friend said something I did too, but I just feel so terrible that I didn't step in and defend my partner. This happened so long ago and it probably shouldn't eat at me and make me feel sick like it does, but I just feel so bad. I never apologized to them either. I'm contemplating texting them and apologizing. I just feel really bad about it.
