why i'm single??

I know exactly why I'm single, and there is not one particular reason for it because it is a situation that has to to with many factors. I don't always mind about it. To be honest, there are the reasons why I'm single. Firstly, I have to learn how to love myself first. Second, I'm always busy. I like to spend so much time alone. Third, I think I am not too mature and I am too shy because I think I am too young to be in love. I need to focus on my study first. Next reason is I am afraid to fall in love with someone because I feel hurt too much when it ends. Lastly, why I am single because I choose to follow my dreams and I am just looking for suitable time to fall in love.
