Honestly, I think this is about a guy who loves someone.
"When I am gone, I hope that you'll stay
Keep me close in memory"- So when he is gone, his loved one will stay with him no matter how long he is gone for and the loved one will always keep him close in their memories
"You can move on with your promise of new
I'll be right here waiting for you"- His loved one might have a new job, or is moving somewhere and he will always be waiting for them.

Thats all I have really.
