that you were fooled and manipulated by him, the first thing they may say is "This guy is really bad", and immediately after that "How stupid this woman is!".
As other friends said earlier, if you had good time with him before, it's time to move on. You may tell the stories to the people who know both you and him. But it's better to drop the matter sooner, rather than later. You will find another man, but you may scare many away if you can't get over with this matter quickly.
One has to pay a price for being too naive, either in the past or in the future. You have to be responsible for protecting yourself.
