Does liking people you like as a friend translate to relationships?

A friend told me only like and be around people who genuinely like you. Is that true for relationships as well? Because I'm learning people who like you show you and you notice little ques like stuff they do for you and some people will eventually get more touchy with you. It's weird like you're just yourself and you're like wtf did I do to get people to like me in any context.
