All it really means is "No thanks. As a person with individual thoughts, feelings, upbringing, circumstances, and tastes, I'm not interested". It's not a statement on your self worth. Not everyone will like you just like you won't like everyone that you meet. You have the right to go for what you want and others have the right to say no. The problem is when you don't go for what you want and you try to take away their choice. By not even attempting or trying to manipulate their decision via deception. The faster you get rejected, the sooner you can move on to exploring others that would accept you. People who go on long stretches of being alone are usually people that avoid rejection.
