The Self-Effacing Predator is a master manipulator. He projects an unsure and inexperienced demeanor - the antithesis of a "player." He is the misleading of all men: his "game" is that he has no "game."
The key to the Self-Effacing Predator is that he lacks confidence to a spectacular degree. But rather than take the road of personal growth he seeks to bolster his self-esteem by self-gratification. The most self-absorbed of all Manspam he will take all that you have to give, promise you the world, then utterly fail to deliver on any of his promises. The Self-Effacing Predator is a high-roller when it comes to Virtual Gifting. His goal is to woo until he sees you falling. Then he disappears - inherently aware that he lacks the strength of character to sustain his promising start.
Consider yourself lucky to be rid of him and do not grieve. He was merely a mirage.
