Was she being unreasonable?

I broke up with my boyfriend a couple months ago and I felt it was time to tell my friend something I had been keeping from her a long time. I wasn't in love with my boyfriend, I was in love with the guy my friend loved who was dating my other friend. She got mad and I said I could control my feelings and I wanted to be honest with her. But she said I could control my feelings and I thought that was ridiculous and I thought she was being a hipicrit because she was in love with a guy who had a girlfriend and she didn't control her feelings and his girlfriend knew that she was in love with him, too. All our friends knew! I said I was sorry and she forgave me and we haven't talked about it since. I'm mad at her for what she said but I'm afraid to bring it up again because she's very sensitive and I don't want to make her mad at me. The guy and my other friend broke up so I don't need to worry about feeling guilty about that because she's over him but my best friend isn't. She loves him, what should i do??? And was she being unreasonable by saying I could control my feelings???
