Forgive the cliche, love by itself is an overused word. When I say "I love you" to my husband, I am saying "I am in love with you".
That no one, except God, is above him. That we are a team, a force of nature, one with nature, is how I feel. I feel this when we are together or apart from one another. That all is right in my soul having him as my partner. Yes, there is a resonation, almost a continuous vibrational confirmation that this person is good for me.
So I must be receiving a positive vibrational frequency - however I also suspect that I myself am vibrating better with this person in my life. Which is probably continuing to give me the warm fuzzies. And giving new life to the phrase of being "in tune". ;-)
