Am I being the bad friend?

So, my childhood friend pretty much hates my boyfriend. Partly my fault because I would vent to her about issues with him in the past. Also, there was a party we all went to where we played a pretty weird game (most of us were strangers) where you vote for the most likely person to do (insert sex act) so we're playing the game and my boyfriend names her for something. The game was weird because everyone had to vote for someone. I can't remember what he said her name for but she was pretty offended he named her at all. I can see where she's coming from being uncomfortable as she already didn't like him but everyone was naming everyone during this game. I think he said her name maybe once or twice max. She later told me he was doing too much and that everyone at the party was staring when he said her name.( I didn't notice, I asked my brother and friend if they noticed and they didn't) . She called afterwards with a list grievances (they've had a handful of interactions) and essentially saying that I didn't respect our friendship by 1) not noticing she was upset and 2) not checking him in the same moment. She claims he antagonizes her everytime she sees him and also said its not always when he's speaking directly to her. During the same call, she asked if any of my friends have had to talk to me about my boyfriend's behavior (none have) and why I liked him. Though, I'm trying to consider her feelings, I think she was being a bit oversensitive in this context. Especially since all of their interactions have been limited and I've actually been there 100% of the time. I'll admit that I do have rose colored glasses when it comes to him but he rarely addressed her directly besides hi and bye since he already felt she didn't like him.
