Most people have a time limit when it comes to love. They feel that if something did not happen already, that it means it never is going to happen. That is not always true.
The Law of Attraction states that we get what we put out there. Some of our relationship failures is because we don't believe that there is love for us out there. We see what is happening in our reality and therefore we gain negative experiences.
First you have to believe in yourself. You have to believe that you are worthy of love. Next you have to believe that anything is possible.
That guy who you are just friends with now could end up being your future husband. You can't stand the guy you work with, later on he might just be the love of your life. You never know what happens.
Just because you are single now does not mean that you will be alone forever. Just because you are just friends with your crush now does not mean that you are not meant to be with him. It's all about timing, fate and believing what you want could happen. Don't listen to any negative people, listen to your heart. No matter what happens always believe and know that anything is possible.
