Help mee

So me and this guy have been talking but we stopped because he wanted to just be friends and it was a bad mess as he was a dickhead so after his friend messaged me and we started talking and etc ...

then me and the friend met up and he kissed me but from that moment I knew it was too soon and it wasn’t right so I said I wanted to be friends as I didn’t want a relationship and now me and the original guy are talking again and he doesn’t know about me and his friend but I don’t know if I should tell him because it will break us up and him and his mate and also we weren’t on talking terms and we weren’t dating or a thing

What do I do ???
