Your empty spaces are always mean't to be filled. There's empty spaces in your brain for more knowledge to come, so what's the problem with having some space in your heart? It just means that you have enough room to grow and love everyone.
I spent so much time trying to forget you. In years I understood that I will never forget you but that doesn't mean I have to be in love with you. When I finally understood that, I moved on. :) wise words of another pinner
