I think it all sounds great. Backing off to give the space that he requested is the way to go. Not to play a game, but rather to honor what he needs at this time. If he reaches out and it feels right for you, you can certainly text back or call back. Keep away from the heavy stuff and just be light and have fun. Time will tell how this will all play out and as you said, you have a busy life. Keep all of that up and doing all of the things you love.
