Std's

Let's say you've dated a guy for almost 3 years. And in the beginning is always wonderful. Then the guy just starts acting extremely jealous. But he's the one that starts cheating. He accuses you of cheating even though he's the one doing it. And you're tired of dealing with his crap. And you say you wanna break up with him. And he goes nuts. Yet, you're still having sex with him. Then you realize he gave you an std. So you leave him and you've been single for about 2 years. Then a great guy comes around and asks you out. You really like him. And he does too. Would you tell him about your std? Or how would be a great way to bring it up?
