My favourite trope has to be:
I sacrificed myself to save you. I didn't plan to survive. I burnt all the bridges. I intended to break your heart with my death, but that would be all right, because I wouldn't be around to see you. I pretended that you'll mourn me for a while and move on. I convinced myself I was going down in the blaze of glory. That my deed was appreciated. That everything was going to be all right afterwards, and I didn't need to be there to see it.
But I survived. And now I have to look you in the eye. I have to pick up the pieces of the life I shattered and figure out how to put it back together. If it can be done at all.
