Just remember, CD, that these little exchanges are never the be all end all. You win some, you lose some, and then there are draws. As Steady mentioned, sometimes the best way to learn is through the mistakes. I don't think this was fatal by any means. You just want to win more in the future than you draw or lose!
Personally, I view it when someone is snarky in replying that it means they care. Thus, the point of "how do you text apathy" is a valid one. We ALL want to say, "Go ___ yourself!" lol but what we have to do is try and take all emotion out of our responses to our WAS. Sometimes that's best done by not replying at all, esp. not to a first text/email/call of an exchange. Then, if they persist, can get a little stronger and reply with something unemotional and boundary laden.
I'm speaking from experience here, as to what has worked with me in the past, not necessarily from my current sitch because it's a little different right now.
