Visitor Visa - B2

I went to the embassy in Kingston Jamaica on 20.12.13

I think I've lost hope and won't be reapplying.

Questions ask
Vo: what is the purpose of your trip?
Me: for a vacation and to visit my brother

Vo : who else do you know in us?
Me: few friends

Vo : what do you do?
Me: I'm an accounts clerk

Vo : how long you work at your present job?
Me: 6 years

Vo : your are in a common law marriage?
Me: yes sir

Then he said I'm sorry can't give u a visa today
I think its because I said I know friends there.. my question is do you think this spoil my chances
Of getting a visa..as this is entered in there system that I have friends there..even tho its not close friends but high school classmates
How soon should I re apply?
