20M discussing my girlfriend.

I'm 20 years old and have been in a relationship with my girlfriend for two years. I truly love her and think she's incredible, but I find myself curious about being single and what that experience might be like. Having spent much of my time in relationships prior to hers, I haven’t had many opportunities to explore single life. Would it be possible to take a break, travel, and enjoy being single for a while, all while knowing that I would return to her after satisfying my curiosity? I genuinely believe she's my lifelong partner, but I also don’t want to look back and regret not having some thrilling experiences in my twenties.
