The attention you receive may be frustrating because it's not from the person you're craving it from, but at the same time it's flattering. It gives you a little source of happiness, even if it's temporary. That attention may cause you to start developing unwanted feelings, even if you don't believe the things that are being said to you. Even if you do everything in your power to overcome those feelings, they take over for a period of time. You can get attached to the attention you receive. But you also have to realize that the person you love is coming back. So, I've been told that I've had an empty void inside me ever since you left. I've done everything to refill it. Drugs, hooking up with various people, just to fill that void. Moral of the story, even though he believes he isn't, he's so ******* irreplaceable.
