Heather, He will continue to text you each morning until you respond. Like a child, he doesn't care if he gets good or bad attention, just as long as mom reacts/responds. You could always just say thanks and nothing more.
I know that you are "itching" to say something else because you've mentioned some of the responses you were thinking about in your head...don't. If you were to say bite me or something else, he would know he got to you and he would continue this same childish behavior.
It's your call as to whether to text back later in the morning and just say thanks or continue to ignore the texts.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
