Here is a little trick I used once when I felt tempted to respond quickly. I turned my phone off and left it off for a couple of hours, immersed myself in an activity and when I turned the phone back on the urge to respond had passed. Worked for me!
However, I usually respond quickly to his texts as he usually does to mine. I don't think that in my sitch there is much danger to be posed by my responding quickly because I think that my overall approach demonstrates that I am not needy and dependant. He GETS this very clearly. But in a case where you are physically separated, this may be one of your only chances to show the "new you", so we each have to decide what works for us.
