Quote from Max E. Pad:
Then when we broke up that all ended and she didnt want me to be apart of his life anymore,(even though i offered) so its no wonder he was always on guard, all of a sudden the guy always just disappears from their life, so why would he develop any kind of emotional bond, it was a defense mechanism.
That still doesn't mean you didn't have an impact on him. Some kids develope a bond and will never show it.
