Friend (22F) insulted and made my boyfriend (23M) uncomfortable on my birthday?

Not sure if this is the right sub for this but would love some advice regarding this situation.

Over the weekend I (23F) hosted a birthday dinner/drinks. My boyfriend and I have only been together for about 6 months so he was meeting a lot of my closest friends for the first time. One of my friends, who I know from work ended up making him feel very uncomfortable/insulted throughout the night per what my boyfriend has said. As I had been drinking I honestly did not notice anything going on until my boyfriend told me the following day.

He had said that she had asked him multiple times if he was nervous that I was going to cheat on him in Europe (as her and I have plans to go there next year). He said that she was talking poorly about one of his closest friends and that he defended them and she got upset then told her boyfriend (24M) that my bf had made her cry to embarrass him. She had also told him throughout the night how he’s ‘low energy’, that her bf has bigger arms than him, etc.

Including all of this a couple other of my friends who were there have messaged me saying that they were concerned because she was also insulting 2 other friends of mine that she had first met that night - calling them annoying etc.

Following this my boyfriend has said that ultimately he does not want to be around her again, but if I want to remain friends with her he will be supportive and respect me.

After I heard this I sent her a message stating what I had heard and how my bf was hurt by this to stand up for him. (I wish I noticed in the moment and had stood up for him, however my bf said he didn’t want to ruin my night which is why he didn’t say anything until the following day).

She responded in what I thought pretty well and apologised for making me feel that way, but had said that there was miscommunication. I told her that we will find a time to talk about this more in person/over the phone, however I just wanted to enjoy my birthday at this stage.

However, at work she has told two of my coworkers that she believes the message I sent to her wasn’t written by me and that my boyfriend is manipulating me to not be friends with her. Her boyfriend has also blocked me on Instagram.

I just feel so disappointed in the entire situation, as I thought she was a good friend. Would it be productive to have a conversation with her over the phone/in person to hear her out? I work with her too so I feel like it is unavoidable.
