I'm absolutely with Shawn on that one (sorry I did not answer earlier but I was on phone conference with BIG BOSS trying to save my butt). Don't text him back and wait for the next one. If he is really concerned - your silence will make him more concerned. He might even call this time and if he does just pretend that when you got the text you were busy and then it just completely went out of your head. Be perky and pleasant - do not let him know you missed him. If he texts you again, this time wait for about hour or so and text him back saying - things are busy here, I'm doing fine, how are you. Simple, to the point, showing him that you HAVE life.
