Is being single a fab life when your 19?

since i started dating i have had only one boyfriend at a time.now i have a guy who i have been with for an year now,he is perfect in all ways and still loves me a lot.prob is all my friends are single and mingling but am not.sometimes i wish i could breack the relationship and enjoy being free and 19,but am also scared that i will not meet someone like him.Q is,is it really that fun to be single and seeing alot of people or is it better to settle.
