Libra who is terrified to be in a relationship!

I have a fear of ever being married, I feel like I'm not capable of making a man happy and in love with me long periods of time so I'm terrified of even thinking about marriage one day. My longest relationships were with a Gemini, who I was with for 6months and a Taurus, who I was with for only a month, I broke up with them. I sort of pull away and break up with them before they get tired of me, some things have happened to me in my life like bullying from 2nd grade til 11th grade when I was forced to leave because of it, in the back of my mind I kind of feel like I am the worst thing that could happen to someone.
Does anything in my chart show why I feel this way? I'm 21 by the way.
