Becky, Your h may have been planning to make a number of trips back to the home to get his "stuff". He may not be planning to return the keys or opener. After all, it's the only mechanisms that he has to get into his home (or so he thinks).

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.
