LONGGG but I need your advice!

Ok ladies I need some advice. About a year ago, me and one of my best friends became 'friends with benefits'. It started as drunk sex, then we started having sex sober as well. Then it turned into us going out for dinners and stuff. And hanging out all the time and lots of sleepovers, etc. and texting all time when we weren't together. The rest of our group of friends all knew what we were doing, but didn't talk about it much. We never talked about dating or any boyfriend/girlfriend talk but still acted like the same friends we'd always been. Then, about 5 months in I started dropping hints and trying to start up conversations about what we are and what we were doing, etc. he never really gave me an answer and always pushed the question away. (He's never been the best at communicating or talking about emotions) so I started to back away a bit then met a great guy and started dating him because I wanted commitment and a relationship and so did the new guy. I just got the impression that my friend wanted to stay friends with benefits and nothing else. I figured he didn't want to date me and didn't care at all when I walked out. We went back to being just friends and still hung out together with our group of friends. Neither of us ever even talked about what happened between us once. Fast forward 9 months, me and my new boyfriend have split up. About a month after I became single again we started talking/texting and hangout out all the time again. Nothing flirty or sexual, I think we were both just excited to get our good friendship back. Last week, were at the bar chit chatting about randomness when out of the blue he starts telling me that it sucked the way I left him and that he did not want us to stop seeing each other and that he was sorry for pushing me away and not letting me know how much he liked me. I was shocked!! Honestly, I never wanted to stop seeing him either I just wanted something more than just a fuck-buddy (excuse the language). So this to me, was awesome to hear. The conversation ended with him telling me he's glad we're friends again and we go back to chit chatting and drinking with our friends. It didn't really seem to me like that was him hitting on me, just us finally having a conversation that we should've had months ago. Hours later, were at his place playing cards like usual. When out of nowhere he kisses me. And it was a super tender, loving kiss-not a typical drunk hookup type of kiss. We ended up having sex. And it was awesome afterwards we laid in bed for hours talking and laughing it was better than it had ever been before. This was a few days ago now, we have hung out several times (but not alone because we were with our friends all weekend) and our texting has slowed a bit. Neither of us has brought it up yet. What should i do?!? How should I handle this?!?? What can I say to break the ice and start the dreaded conversation up?!?!? I NEED YOUR HELP
