You can use QUERER to say I love you, but it sounds awkward and It seems like you want just have sex with her. And I think this verb used for this purpose turn the woman into an object. So if you want to say that you love someone you just have to say "Eu te amo", but if you want to say "Eu quero você." make sure that the girl really love you otherwise she is supposed to think that you just wanna have sex with her.

I want you - Eu te quero. You could say to your girlfriend or wife - Eu te quero , She understand you love her.

Hi :) The verb "querer" is only used in brazilian portuguese. In Portugal Portuguese we only use the verbs "amar" or "adorar" to express our love . I hope I helped you

This is a very interesting question! "Querer" with the sense you ask is used in spanish language. In portuguese, if you say "Eu te quero" has a sexual sense. If you love the person, you can say "Eu te amo". If you like the person, you can say "Eu gosto de você". Français x Portugais Je t'aime = Eu gosto de você Je t'adore = Eu te amo, ou Eu te adoro
