Why would a flirty guy not flirt with a woman he is attracted to?

Anonymous

I'm pretty sure this guy finds me attractive. In the beginning he was friendly to me but now he has become very cold and distant, sometimes bordering rude, to me. He is very polite, confident, popular with girls and not shy to flirt with attractive women he has known for decades. He has a girlfriend and I am not interested in him, I would just like to know why he treats me differently to other women.
