It's not as simple as they all seem to think it is, that's what I tell myself. It's not that I don't care, it's that I can't afford to. I know all too well how much it would hurt if it did. That's the trouble with being immortal, I know better than to just risk it or to hope that everything will turn out OK because I've done it before, seen time and time again that it doesn't end up OK. So I close myself off from the world and tell myself that nothing really matters even while there is a huge part of me screaming that it isn't true.
I know he loves me and I hear him as he tries to cry silently some nights when we are in bed together. I know every emotion he feels because I have felt it before. I felt it with the Doctor. That's the reason I came back to him, you see, not because I'm cruel or selfish but because after spending time with the Doctor again I remember how it feels. I know that something is better than nothing so while I can, I will give him everything that I can even if it will never be enough.
