Sure they can disappear and then make contact again and some even have spurts of communication and then go quiet once again. It's normal mlc behavior.
When he does make contact, listen to what he has to say. Sometimes they tell on themselves w/o even trying. LOL!
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.
