How to learn to be a better person?

Seriously you need to learn to be single. Not just single in the sense of being between men, but single as in alone. When you are alone you can really think about who you are and what you want for your life. Then you will know who you are and be confident and then guys will see all those cute things about you and really like you for who you are, and hopefully then you will be able to find the right guy for you that makes you feel secure in a relationship so that you won't be clingly or jealous or emotional. The reason you feel that way is because you have been in relationships that make you insecure.
