Absolutely. Personally my feelings and thoughts are it may be a good idea if the individuals, especially in the case of a coupling, have a shared definition for love first. I say absolutely offering testament of Love with a person I have never met, have had a three year relationship mainly online via email, and etc, and have the perspective of Love being eternal.
However, for purposes of understanding Love we both share a mutual agreement and acceptance with both trust and faith with the explanation by C.S. Lewis and his published work - The Four Loves as a guide. And, the understanding all exist each as love while all must not be present for love to exist.
A) Storge - affectionate love
B) Philia - friendship or sisterly/brotherly love
C) Eros - romantic love
D) Agape - unconditional love
When questioned by some with social interactions of our relationship of being Loving I always ask questions for offering explanation, which seems to work for me. Simply any of these following:
1) Are you an atheist?
Next, then love is only a process of stimuli, motivation, behavior, commitment, and having acceptance of those with trust and faith in your relationship with experience and reason.
1) Do you Love God no matter your definition?
2) Have you ever met God?
Most likely many will have more to share with views of difference and likeness, so I ask this only be of acceptance being a subjective perspective and not necessarily universal.
