the problem with English is that they don't really have expressions for those kinds of things, they don't have too much options, for example in Spanish we say "te amo" for a person who you love in a romantic way but we say "te quiero" for someone that you love as a friend, but in English is different, what you can do is only say "I like you" because it is not as strong as "I love you" and it doesn't imply something romantic
