Should we get back together?

Ok so I have a guy best friend and me and him dated during the summer and no one knew and we both wanted that but we broke up before school started, and let me tell you I was hurt so was he and bro me and him still remained as best friends even though we broke up but at the same time we both still had that connection and we felt it. But at one point I felt like I wanted to move on but I regretted that because I still had those strong feelings for him. Even he did too, don’t get me wrong he treated me good but the reason we broke up was because lack of communication. But moving forward to today we been talking like that like if we are gonna get back and we had made out before and I don’t know if we actually going to become something again or we just friends with benefits. Ugh I need advice. Should I talk to him straight up or just see where things go?
