It’s better to have nobody than someone

If you ever find yourself in that position, get away from them. Remove them from your life. They’re ungrateful, unrepentant, and usually narcissists, but the contribution they make to your life is showing you the shining example of who you don’t want to be. ~ Jim Ferrell 

Some people don’t know how to be alone. I rather be alone and happy than with someone and miserable.

It's better to have nobody, than to have someone who is half there, or doesn't want to be there.
