Love fades if communication stops, because I believe its vital in any kind of relationships, that is one way to express what you feel and also a way to exchange of ideas. Also, if trust between each other becomes weaker care lessens. It's like everything suddenly stops. The next thing you know you're not happy anymore.
yes of course, love fades because when the other partner is done something wrong on his/her partner it will break the trust and it's hard to put the pieces back.
For me, yes .. since everything in this world is temporary, so does with love. It fades especially if both were not taking care of it.
love in itself doesn't fade, our feelings change every now and then though.
