The English language is very limited when it comes to words having to do with love -- we only have the one word. Having only one word can present a problem when it comes to understanding what someone is saying when they say "I love you."
Love is a very powerful force indeed. The more we tune into it inside ourselves, the more we can channel it in any moment by aligning with the feeling state, and it leads to bringing that power into being.
What self-efficiency means is that we get into a relationship not because of neediness or fear of loneliness. It is more of a sense of finding more joy rather than filling up some empty hole.
