I slept with my bestfriend's finance on his wedding day, my gf's mom and aunt as well, what should I do?

Take a look at my pic http://www.myspace.com/sanjaywilliamson... I am y and smart jamaican. I am planning on tell my bestfriend, cause he has been hyocritical to me in the past, that way i could get back at him. Also my girlf's mom and aunt and I had a 3some, so we plan on telling my gf that she cant satisfy me again, so me and her mom and aunt decide to hitch. Im a model, college graduate and heir, so i guess i can do about anything.
