My friend called my husband useless while he was recovering from a vasectomy. How do I handle this?

On today very hot day, my friend asked to come over to my house with a pool to escape her stuffy flat. I said yes. My husband is home recovering from a vasectomy, which he got so I would not have to take hormones or for us to use condoms( we both hate them) and the condoms always give me burns.
I chose to garden that morning while he rested inside with an ice pack and gamed. He brought us drinks and suggested I stop because of the heat, but I wanted to finish before the rain, (there is a storm later and I want to have a nice garden so we can hang out there tomorrow) anyways so he went back in.

My friend immediately started attacking him, calling him useless and horrible, saying I should leave him because I earn more money, that I have internalised misogyny, and that I am being abused and cannot see it. I calmly explained that I chose to garden, he just had a procedure, and he is a supportive partner(he really is), but she dismissed everything and went inside to say the same cruel things directly to him.

I asked her to leave and she did, but now my husband is doubting himself, wondering if he should have worked in the garden and if he really is a bad person. I told him she has her own issues and we are fine, but she keeps texting me feminist quotes and telling me to break up with him. I am ignoring her for now.

I need advice on how to shut her down for good and how to reassure my husband, because I know I have a great partner and I am happy in my relationship. I am also a feminist and so is , my husband , and yes I earn more because of his support , the amount of mental and emotional and actual support he creates in my life is why I’m very comfortable.
I got sick end of 2023 that man took care of everything, me and my family and all our pets ❤️ not once did he complain or appear frustrated , also i wouldnt know I was unconscious most of the time all I know is whenever I woke up he was there and when I went home everything was done for me.
With my friend whenever I said these things she kept saying I’m just self convening and I’m defending him because of my own internalised self hate.. I am like girl what! Thats not it Whats happening …
