Does my best friend want to steal my boyfriend?

[Look]

My best friend has always given me the greatest life support but currently she does not approve of my boyfriend. My boyfriend on the other hand is a doctor, single, lives in a huge home with a 7 series BMW, he is compassionate, loving, generous, he is a great conversationalist, he is a great person in every way. He has a great caring personality, he is successful, and it does not hurt that he is tall, dark and handsome and he has quite the physique. But my best friend does not view him the same way. She thinks he is just using me for a good time, that he is too private and too controlling-which he is not. She tells me he is Muslim and he will remain true to his faith and I cannnot fit his lifestyle and she says Paki men want submissive wifes and their parents always force them to get arranged marriages. She tells me to break up with him because it wont last. BUT at the same time I caught her flirting with him at the party and I mean she was all over him.
Girl Keyweb I know but I am worried about this.
