Is it actually a compliment or just a threat?

So some guy asked my friend if her boyfriend “knows how to deal with her.” I told my friend my actual reaction. I said to her “he asked because I think he wants to fuck you.” She told me that that’s not what he meant (I know men and how they say things ) she said “I don’t know how to deal with him he’s a bit strong headed. He’s not afraid of me or thinks I’m intimidating.” I got it I only said what I said. <br>How can I deal with her bf? Not really sure. Any suggestions?
