Was I an ass for speaking the truth about my friend’s guy friend? I had to say something about it!

So I noticed that the guy one of my good girl pals has been hanging out with only using her for her money. Like for example when she asked him to like hang out for a barbecue, he said no. He never wants to hang up with her for who she is. Honestly I don’t think she’s safe around him because he uses her for stuff, her money put her into a dangerous situations. He never wanted to hang out with her before. We can’t really stop her because it’s her choice and she’s an adult. She asked if we wanted to hang out with him but I bluntly said, “He doesn’t wanna hang out with us. He only wants to hang out with the girl that has lots of money.” She looked at me shockingly and said, “What’s that supposed to mean? He likes me and he enjoys my company.” Then I said, “Yeah to only use you for your money to get ahead of his desperate life.” With an angry tone. She was like, “Shit (my name), th….that isn’t fair. I think you’re just jealous of our friendship and you will have to get used to it! Back off!” I was just telling the truth. Sometimes the hurtful truth needs to be said. I’m her true friend and I am just looking our for her. She found out I was right about him. She said, “I feel stupid because you were right about (his name). He WAS only using me for my money. He didn’t even comfort me when I was in pain. He just left.”
I told her, “Hey you’re not stupid. You just have to realize who your true friends are and WE’RE true friends that will always be there for you, thick and thin. She was mad at herself because she refused to see the truth.
I have nothing to be sorry about right? I was not rude. Good friends tell you the truth.
