Funnily enough, while "bien" is also positive word, it's indeed used to lessen the power of "aimer". That's the kind of stuff native speakers don't even notice but can confuse everyone else.
But it would just never occur to me that adore could be a synonym for love. It just doesn't strike me as such per se.
There are some languages, for example, that have a literal translation of "I love you" but the semantically equivalent expression, when translated to English, is "you are precious to me". It would be awkward to express the English semantics via literal translation, as it has different connotations. The meaning is more important than the literal expression.
The literal translation of "I love you" denotes something closer to "desire" in English.
I was always confused as a kid because the English word "love" is the same translation for various Greek words like ἔρως, ἀγάπη, and φιλία which used to give me conniptions when doing translations in school.
Likewise Sanskrit and modern Hindi make distinctions impossible to differentiate in English (and not just in love -- I speak English with my relatives in India except for words for how people are related to each other, something English doesn't seem to care about at all, as it only has a tiny number of pretty uninformative words like cousin, brother, aunt and so forth. Oh yeah and food words, but that's not English's fault).
By and large English is an OK language, with a moderate-sized vocabulary handily full of loan words, but even though it's the language I've been speaking longest, as I get older I find it less and less expressive. My wife and I used a mélange of three different languages different ones had different ways of expressing certain things we wanted to say to each other.
Thank you for elaborating.
I don't think Je t'aime bien its the same as Me gustas and definitely je t'adore doesn't convey the same emotions as te quiero
