No. If it changes, it was never love in the first place.

Real love can not be change with time.

Yes, it can. Look at the floating clouds, it changes like that-- every shape is adorable. It also wouldn't be predicted.

Yes, love can change in time, if a peson can change himself in time.

We love each person for different reasons and in different ways. The Greeks had four words for the kinds of love. and our love for one person can change, even if unfaltering, as we learn and experience more with the person. that is my feeling anyway. :)
