Hello thechamp,
I think you're being too harsh. Maybe it's just me, but being the alpha male isn't just about being more aggressive than his boyfriend or whoever. I think it's about finding a balance between "rage" and being able to overcome the others in intelligence.
I would have said something funny, like, "let's test your boyfriend then", which will make her curious about you, because she will be doing something "prohibited" and will not make her think you are being extremely aggresive.
