No you shouldn't die! Maybe it wasn't anything you did wrong. Maybe he had a low self esteem and didn't think he could measure up to you. Who knows what was going on with him. But try not to let it beat you down! I've avoided people's affections before when I didn't feel that I'd "fit in" with their lifestyle and such. It had nothing to do with who they were as a person, just my own perception of myself. Please take care and not let this define you!
