WHY IM I STILL SINGLE!!!!!!!!!!?

I'm a 24 year old female living with my 3 year daughter in St. Louis Mo. I'm a very attractive, strong will, independent woman, who works and goes to school my girlfriends call me super woman. I've been single for quite some time. I do go out on few occasions on dates that where set up by friends and family but at the end of the day I go home with no boyfriend. I don't know what am I doing wrong and I don't know why I'm still single any guys out there got incite of what would be wrong or can be corrected
