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.
