Things are always going to change, whether you want them to or not. The grass is going to grow as well as the people you love. Once this growing begins you come to realize how strong that love really is... or isn't. You can try to hold on to that love until there is nothing left, but eventually letting go is a must.
Once the letting go begins, more change begins. You reinvent yourself as a new person, not the person you were when you were in love. And once this transformation is finished, you are changed.

Change is inevitable you have no choice. How you respond to the change however, is your choice.
