I might've came off wrong, sorry. Typing for me isn't the best form of communication.
Insecure people, on the other hand, need to have someone out there, somewhere in their lives, that they haven't let go of.
Also learn to let go. Relationships come and go, we're human and they don't always work. Often, they never work. All things pass.
If you have unprocessed relationships, it's because you're still plugged in, or connected to someone, and they are not connected to you. They have hurt you, so there's a Karma there, but the Karma is always with yourself. It's not with the world. The Karma center is inside you. The only way you can make a peace with that person that hurt you, is to make a piece with yourself. When you do that it's clear, it's that simple.
