That sounds perfectly lovely, but is a heap of nonsense.
We did not live previous lives and have not met anyone before we were born.
Love is what? Something you automatically feel? You can hate someone and still show them love.
Paying attention to someone, helping them, praying for them, helping them guard against wrong is a lot of what love is. It takes time and practice. You don't "love" someone you met five minutes ago. You have a crush on them. Sometimes people fall right back out of their great "love" the first time they see their beloved eat spaghetti. LOL
