Is this evolution?

Six years back she had come into my life with some books, innocent smiles, and the ego of being a beautiful girl. She was sweet and well-behaved. In some corner of heart she could easily make her presence felt with increasing heartbeats. She was like a stream, dancing happily with rippling waters and flowing ahead. On her way she had curved where I stood in the world stage for a while and moved ahead once again happily dancing with rippling waters. Life was beautiful with her. Life is now also beautiful because once, life was beautiful with her.

I cannot love now because I am above the permitted age but I can feel romantic love as a shadow because once they were real for me. This is evolution or growing old to embrace other facets of life where rose does not bloom nor life stops with the after effect of a closed-eye kiss?
