I think I said it earlier on...do not contact him again...let him come to you. Right now, he needs some space and time to get out of whatever he is so focused on. He knows you love him, so give him that space for a while. When he realizes that you've not been in touch for a period of time, he will text/call you and want to catch up. Until then, keep the focus on you, your daughter and that cute little pup.
You've got this!
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.
