I'm queen of attention to details

I can see that one of my dearest friends is falling in love with a guy who is committed to another girl. The guy keeps on pursuing her and although she knows that he has a girlfriend, her emotions are too high up in the sky to even think about the situation. I love my friend so much that I just want to yank her hair away from that person and lock her up in a room until I slap some sense out of her. If you know me personally, you would know that I often don’t have strong reactions to things and situations. I’m the “whatever happens, happens” type of person. But I cannot keep quiet in times like this. When I start caring for someone, I will go the extra mile to make sure that I do my part in being a good friend — because a good friend does not tolerate the mistakes of a friend… And a good friend helps her friend think when her brain is down the drain.

I wish I can find the right words to say when I talk to her later, because I don’t want her to think that I am controlling her. I am not against her. How do I make her understand that despite my defiance against her love interest, I am actually on her side?
