Why does my friend isn't supportive of me?

I have a friend and I always tell her how much I like my crush and she always say my crush deserves hotter woman, someday he will marry a hot woman because he could do better. its true he is hot and Im just average looking and It hurts cuz she knows I like my crush and she's giving me those comments now I feel insecure and I don't know why she isn't supportive of me
