More than possible, in my experience. *True Love* is given by most dogs, a few cats, & more than a few people. On the other hand, *Unconditional Love* is given by only One, as far as I know.
Of course there's true love on earth. Do you have children, Joe? My husband and my kids are my "true loves". Also my little dog, Harry...but he died in 2017 and my heart is still broken.
