Coexistance is a state of celebration achieved with loved ones. Coexistance shines the most brilliant colors on other beings, illuminating their beauty ever more clearly.
Coexistance is a state. Love, on the other hand, is not a state.
I will avoid a clumsy attempt at defining love, but coexistance is tangental to love. To feel as though love has ended when coexistance changes, is interrupted, or ends is to do yourself a great injustice...to simultaneously undermine both that love and the future possibility of coexistance with that loved one.
