I don't believe that "all things come to an end". I think the mind is a powerful tool, so long as you patronize it. I think that your life, your memories, you thoughts live on for as long as you feed them the breath of your soul. I think that your love for a thing or person doesn't end either; it is endless and as strong and as beautiful as it was the first time you allowed yourself to feel it.
I think very few people are courageous enough to carry on thinking, feeling and loving a thing. It can carry a badge of hurts that temporarily pain you... but there is something beautiful and authentic in that. Certain things in your memory are for always, no matter how much they are "felt". 
Not "all things come to an end"..... even when they do...
