NC is for you to focus on you, not H...and I know, been there...nearly wore out my "click finger" clicking refresh on my email, looking for some contact from W...it doesn't help. Turn off the phone, turn off the computer, something for a few hours at a time so you won't be tempted to check (that's what I had to do) and get busy with all the stuff you have to do and try to forget about Mr. Space Cadet for a while.
Focus on the kids and you.
Easier said than done, but we all get better at it as time and practice go along.
Hang in there!
