Simply, as always, if you show it hurts, then it'll just keep being dished outmore.
If you do feel the "need to respond", and actually now that I think about, maybe you should, do it in a way he wouldn't expect, like a simple "lol" or something, just to throw him off track.
Taht said, why does it hurt? Because you let it, you haven't let that go and accepted it. Neither have I and it shows, and what do I get, more and more of it rubbed in my face.
