<human>: Can you succinctly summarize the text in 1-3 sentences?

She lives in my town, but goes to college in another state. She has self-esteem so low, scientists should study it. I tried to show her she was worth more than she realized, but she shut down my efforts, declaring me "too nice" to deserve being around her.

And now she's been texting me about her fuck buddy who treats her like shit. She knows it's a problem, but thinks it's all she deserves. All but one of her boyfriends was the same way, and she literally broke up with that one because she feared he would see he deserved better.

I know I can't "fix" her, but I want to do what I can to set her on the right path. Any help here would be hot.
<bot>: female friend thinks lowly of herself, seeks out guys who do their fair share of reinforcing that, and I want to help her.
