Please give me advice

I'm probably gonna get shit for this but what the fuck ever. I'm married. But 6 weeks ago my world got torn upside down. I found out my husband cheated on me. And I left. I met this guy and I fucking slept with him. He was my best friends cousin. And we're actually great friends now. But fuck me if I don't have feelings for him already. Like this man is so great. He's a gentleman. He's never said ANYTHING mean to me, he's so funny, and great looking. But sadly we've both been burned pretty bad in past relationships. And he's not looking for anything. And I know I shouldn't be either. We like each other though. And this is so hard for me. I wasted 3 years with my scum bag husband and didn't even realize how great guys like him were out there. What the hell do I do now
