<human>: So the girl [21] I'm currently seeing recently told me that she really doesn't deserve me. She has the conception that she's a terrible person who makes bad decisions and will inevitably hurt me sometime down the road. For a little background, we did date briefly last year but it ended because she hooked up with an ex. We never had any talk of monogamy, but I was still hurt by it and she felt badly too. Important to note is that we've been really good friends for years now, so we have a strong connection whether sex is involved or not.

 So fast forward a few months and we decided to start dating again, and things are way better than they ever were before. We both feel closer and things are going well. Then the other night we had a intimate conversation where she practically broke down into tears and kept saying how much worse of a person she is than me, how all the rough things in her life are directly the result of her making shitty decisions, etc. As an aside, she is not a dramatic person, she's down to earth and just generally always has things under control. So it surprised the hell out of me when she was laying this on me, as that had never come up before.

The biggest thing I'm worried about is that her whole conception of who she is as a person inevitably ends up in a self-fulfilling prophecy, with her self-defeating decisions further influencing and reinforcing more and more. So I'm honestly afraid she's just going to do something really shitty just because she believes that she has to and then we'll end up further apart than ever. Does anyone have any thoughts to share from similar experiences? I'm all ears because I love what we have now, and I'm looking for any way to just build her up so that she doesn't have that looming fear that will at some point lead to her forcing our splitting up.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: SO thinks she doesn't deserve me and will follow her own self-fulfilling prophecies to bad decisions and heartbreak unless I can figure out a way to stop it.
