<human>: I broke up with the girlfriend I met online about 4 months ago. We never even saw one another or talked in person because she's several states away and neither of us is in a position to travel. She was always quite needy and vulnerable.

She says she still wants to be friends because she has no one else, but she's sending me a ton of messages about how her life is pointless and she hates herself and just wants to die. She's really freaking out. I feel like this could just be necessary venting but I'm so afraid she might really harm herself. 

Is it possible to be "just friends" after a breakup? How can I help her get past this when we only ever communicate via text messages? Should I do something about her threats to harm herself?

I feel so terrible about this but the relationship would never have worked out. Even though I feel like shit I know it was the right thing to do. But now I don't know how to help her in the aftermath. Any advice is greatly appreciated.

Can you condense the text into three sentences or less?
