My best friend is super mad at me over the dumbest thing ever

My best friend is dating this guy and he has a cousin who she thought I'd be really compatible with. She set us up on a date which we both agreed to. The date went so well. We decided to see each other again. The next date went really well too and we decided we'd have sex. Well when it came to it, I told him to put on a condom. He said he didn't want to and asked why. He knows I have an IUD. I told him it's because idk if he's clean or not and I'm not trusting him enough to tell me the truth and that he gets tested regularly. So we didn't have sex because he wouldn't use a condom. I had some btw. I guess he told his cousin who told my best friend and she's upset with me for this. I'm not sorry and why should I be? I'm just looking out for my health. She said it embarrassed her but like??? Lol. Is she trippin or what.
