When you hurt me and I'm okay about it, it doesn't mean that you've taught me to be stronger, or improved my outlook, or...done anything positive, actually. If you hurt me and I don't fall apart, it only means that you were the last connection I had to my feelings, and that by cutting it off you have cut the last of my ties and sent me drifting away from everybody in my life. When I actually love you and you actually hurt me, any "okay" you see, and tell yourself you've made me strong and wise enough to achieve, is actually just a slow paralysis of the heart, a spreading numbness that, honestly, scares me more than any pain.
Heads up. The silent treatment is actually never helpful.
