How to start fresh with an ex

Hi everyone, I’m 27 and me and my ex just rekindled. Little back story we got together when I was 21 & he was 22, together for a year & a half. I’ve never fully moved on from him, we’re each other’s first love, it was just toxic we were BOTH immature. We could never leave each other alone until I stopped responding to him, that break up was the worst break up ever, I felt like I HAD to leave because it was arguing every day.

For years we haven’t had any contact and never thought we would ever cross paths again, but here we are. I actually reached out and we’ve gone out to a couple of dates, it’s been two months and I’m so happy to see how much we’ve matured, we’re different. We’re better but I’m always scared to go back to not trusting each other. We both talked about starting fresh and “doing it right” the thing is I don’t know how to do it “right” this is my first time ever going back to an ex.

I can honestly say this time around we’re way better to and for each other. It feels wayyy smoother this time, our communication is way better and we’re definitely on the right track.

Any tips/ advice? I’m open to anything
