26M - my 26M boyfriend's friend is planning an intervention to break us up

Hey yall,

Essentially my boyfriend didn't like a joke I told in a social setting and mentioned to another person in his friend group that she doesn't like me and him together and given the one joke I said, thinks it's appropriate for her and his friends to hold an intervention with my partner to try and encourage him to break up with me.

My boyfriend told me about this in an Uber on a way to a party and I remained fairly silent but supported my boyfriend because I know this bothered him a lot. I didn't really know what to say but he did show support for me as he recognized that she is completely out of line and he may not even co-der being friends with her anymore because of u she's been doing behind my partner's back.

For some context, my boyfriend's friend who is orchestrating this "intervention" is a very negative person and looks for any excuse to complain about something. Very critical too. Since my boyfriend told me about this, l've told him that I support whatever decision he makes about staying or not staying friends with this person but I can't lie, I'm still uncomfortable and angry with the situation. And until he makes this decision, it's possible that I may see her from time to time in social gatherings.

So my question is this:

Do I confront her and try to have a private conversation with her when I see her next to clear the air? Do nothing and let my boyfriend deal with it? Or something else?
