<human>: Can you give me the gist of the text in a nutshell?

Hey I really need some advice, 
My Girlfriend of 2 months, although we've been "seeing" each other for about half a year now, has big self conscious issues surrounding her body and sexual intimacy, she hates me looking at her body and always hides under the sheets when we get intimate.

For a long time I've wondered why, she has a beautiful figure and everyone I meet comments on how good looking she is, although she slowly improved I could never understand the reason for this problem.

 Until tonight when, after an argument, she told me that a past boyfriend used to call her ugly and other horrible things about her body all the time, especially after they broke up.

This clearly makes a lot more sense to me now but I am unsure what I can do to help her, apparently she's talked about it before but, I quote, "people think its ridiculous but nothing has ever been done about it". 

I hope someone could perhaps relate or have any advice on the best thing I can do to help her?
