Being single is underrated. You have complete control over your time, money and energy. You can chase your goals, make plans without explaining yourself, enjoy your own space and live without constantly adjusting your life around someone else. The best part is being comfortable on your own because once you are comfortable alone, you stop settling for people who disturb the peace you worked so hard to build.
You spend years thinking life will eventually give back what you gave it until life teaches you that it doesn't always work that way. You can give your best and still get less because doing everything right does not mean things will go right. You keep waiting for life to balance itself out until you realize some things never will and you have to keep living without the ending you thought you were owed.
