Why do SD's poof?

Or SB's for that matter.

1. SD's

Their wife found out
They got a better deal elsewhere
They had a change of heart
They just got tired of the SB
They realized that SD lifestyle is not for them: maybe it costs them too much money that they don't have or they just didn't realize at first what the word 'sugar' refers to. This one actually happens pretty often.

2 SB's
SD was too ugly, smelled bad, or had missing teeth
SD lied about his age or financial status (happens all the time)
They had a change of heart
They didn't realize what the word 'sugar' really means, he he he
They got a better deal elsewhere
They just wanted to try this sugar thing just once, to be able to say they fulfilled their curiosity
Maybe they are scammers: they got what they wanted, they leave and move on to the next victim
Some are just way too young, and they just flake. I remember flaking on some dates at that age to, so no hard feelings

SB's feel free to add more. I will add as I think of them
