What is wrong with me?

Not having a boyfriend does not in and of itself mean that there is anything wrong with you. And, there may be some interested who just haven't gotten the nerve to let you know of their interest yet. Enjoy life, be happy with yourself and your friends, and a boyfriend will eventually come into the picture. If you live life focused on finding a boyfriend you will either settle for less than what would be compatible when the first one comes along, or act and look desperate, which is a guaranteed way to scare any potentials away. Being comfortable with yourself is the best boy magnet you could have.
