Yes, it's very rare for a foid to befriend a non-fag male.
However, it is very common for foids to use orbiters for social validation, emotional tampon, personal favors etc.
If he were ordinary-looking she wouldn't show him to you.
That is a way for foids to brag about how high her SMV is, since she can snatch a good-looking dude.
That's like a man showing his bros a photo of his most prized toy, car, boat, pokémon card, etc.
Foids use orbiters like OP to derive the pleasure of social validation.
OP is being used as an emotional tampon.
Wanna try an experiment? Try to extract from her some social validation for yourself by telling her about your day, yourself, your stuff, showing your clothes, Yu-Gi-Oh cards etc. and ask her to say positive things about you, your stuff, your ideas, your choices in life, your dress style etc. and see how quickly she loses interest in talking to you.
