Relationships last longer when no body knows your business. ~ plus it's not like it will be kept a secret.people you don't even know will know all about you and what goes on in your relationship, like my bff for example :p
They say that you find yourself, try to become a better person all your shitty friend they will be gone. God will not allow you to work on you, let you get better and heal and keep bad friends that influence you the wrong way. that is not going to happen.
