What happens is that they do go dark for days and even weeks and/or months...but they always contact you when they need or want something. He may be testing you to see if you will actually weaken and contact him. That would fill up his ego kibble bit tray because he would then know you are still there waiting on him.
Your h is a grown man and doesn't need you to worry about him. When he's ready, trust me, he'll contact you. Continue as you have been, keep the focus on you, find things to occupy your mind and time. When you take the focus off him and put it back on you, that's when the winds of change will shift.
Continue as you have been.
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.
