If you aren't happy being single you will never be happy in a relationship. Get your own life and love it first, then share it.
If you're single, focus on being a better you instead of looking for someone better than your ex. A better you will attract a better next.
Being single doesn't necessarily mean one is not wanted. In many cases it means that one knows what they want and if they can't find that someone special then they'll remain single forever because they're OK and happy with who they are and just want that someone special to complete them and take their happiness a higher level.
“Being single” is a term used to describe the state of a person being single and not committed. A single person unlike a committed person is not involved in any relationship. A single person has a multitude of friends and acquaintances and enjoys his single status. Being single is a privilege for many, since they are free to live life individually, without the pressures and expectations that are often associated with a committed relationship. Life is truly an unpredictable affair and you have no idea about how it can change at any point of time. So, people some people prefer being single rather than getting committed to someone. Dealing with relationships and making them successful is not everyone’s cup of tea. Relationships require emotional investment, as well as a lot of time to make things work. So, staying single is what people prefer usually. Stephanie Mills had once remarked, “I enjoy being single, but I loved being married.”
