Meeting the right person at the wrong time???

Im 22 and i never thought id settle down till in my 30s. Now I’ve been dating this guy for about 8 months now and he is the only boyfriend I’ve had and he’s just so sweet and just a great person. But now I’m kinda freaking out that maybe i met the right guy too early? I kinda feel like maybe i wanted to explore more and date more people before settling but I’m also too scared if i break things off i might regret it in the long run. Do you guys have any suggestions? Help a girl out!!! Pls <3
