Is staying single forever good?
Being single is a sign that youre good at being alone, and there arent many people in this big world that can say that about themselves. Its not about being alone, its also knowing how much you have to give to another human being, because being in a relationship does mean that you have to compromise some things.
Can we live single forever?
Is it OK to be single forever? Absolutely, if thats what you want. Dont let anyone tell you that you need to be in a relationship to be happy in life. In fact, its better to commit to being single until (and unless) you meet someone who changes your mind.
