Most people who want to RELATE with you only have one means of foundation. What they know or did know about you. Especially, if they are no longer able to be present in our current or future purpose.
People use the past as a point of reference. Most people who we've eliminated or deemed unproductive for our NOW still want to feel connected. So, they hold onto past information as a means to still be connected, control or manipulate the other individual.
Here's the way you make sure that doesn't work: Make sure that the information, past point of reference, last log in time doesn't have a connection to where you CURRENTLY are. It's like someone having an old phone number when you've changed it. They can dial, but the call will never reach you.
