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".

Je t'adore = Eu te amo, ou Eu te adoro
