It really hurts to think that it could be as simple as that. That you can give so much and be so trusting and adaptable and get nothing in return, just a 'thanks but no thanks'. But you can't have an open wound forever.
I have to remember this. I have a tendency to want to hold on to people forever. And when they don't want the same, I become hurt, and react by building walls. I am grateful for the time some people gave me.
