Long distance relationship help?

I used to date this guy far away from me but we broke up because it wasn't really working out and everything was complicated in m life so I needed to focus on one thing. But now everything's fine and we've been talking and I told him "I still like you, I always have" and he told me that he likes me too. I like him a lot and I want to date him again but I don't know how to keep the relationship going. We are only 14 but we've known each other for so long and he's always there for me even when I'm having a bad day. What do I talk to him about I don't want to sound boring and awkward .
