Confused to the max

I had been going out with the guy for a year and a bit. We started to both feel a bit boring and things were just passing along day by day wth no excitement, experiences or anything, we talked about everything and things got too much that we broke up. I met some new people and we all became super close mates withing like 3 weeks or so, there’s this one guy I get along with like two peas in a pod, and the other day he told me he was really into me and then kissed me, and now I’m confused on what to do because my boyfriend and I broke up less then a few weeks ago and also to both sxperience new things and not hold eachother back. I don’t know what to do because I love having this guy as a friend and I’m worried if something more happened I would loose him and the new mates I made. but I guess I can’t have him as a friend when he likes me.. any advice is appreciated
