I just don't get it...

I have no idea what I've done in this life to deserve to be disrespected by all the guys that I date... How is that possible that they all disappear or leave? How is it possible that they don't fall in love with me? Why do I always choose the ones that treat me this way? I don't think I have cried as much in the past 5 years as I have in the past 5 months.
