If he's trying to change you into a person that you are not. Bes, he doesn't love you enough. He just simply love the idea of loving you.
Love accepts the whole you!
Just a note from a Filipina with brown skin since birth:
There is no problem AT ALL sa mga gustong magpaputi. The problem is when whitening brands make us look "kaawa awa" dahil lang maitim kami. Kasi, hindi po kami kawawa, maganda ang kulay namin.
