Most Helpful Girl
Think about it this way. It's been a month of no contact from her. Then suddenly bam? I get it, she's having issues in her life that are stressing you out; however, you are not the person to turn to. I don't feel that she wants to be back in a relationship, she just wants someone to make it all better.
I agree that you shouldn't be the one to help her. If you do, she might get back with you, temporarily, until she is back "on her feet". Insert another catastrophe, and she'll run back again.
It's up to you... Do you wanna be THE ONE or just the fall back guy? Make some standards and stick with them!

I'm siding with your parents and friends on this. I'm sure to her some issues are bad, but I believe she's emphasizing the urgency to get you to respond.
The anger she's experiencing in you not responding is her own doing, and she sounds a bit controlling if you ask me. If her friends are shitty, then that's also half her fault, since you have a choice who your friends are and who you choose to hang out with.
You seem like a really good guy, and there's nothing wrong with being heartfelt and sensitive. You gave your heart to this girl, and apparently that wasn't good enough. She didn't seem to be in such a state of "urgency" when she broke up with you to most likely pursue someone else. And now that guy's used her, she's sad and lonely and feels like using you for her benefit.
Of course you have feelings for her. You loved her and cared about her and I'm sure you still do. However, she's now interrupting your healing process, making it that much harder to get over her and move on, where you can meet someone who truly gives a shit about you.
Let her be mad, and as tragic as things are in people's lives, everyone has to deal with them, and it's not your responsibility to help someone who shit on you.
Don't call her back. Just ignore her.
