Wat do i do to get him back ?

How many time do you have to be hit in the head with a brick. If it did not work out the first time what make you think it will work the second time. He got what he wanted from you and it must not have been as good as the thought it would be or he would have kept you. Forget him and move on and do not be so free with what is between your legs next time. Good Luck.
