I just came upon a situation, this person I "met" is homeless what should I do?

I don’t know if anyone reading this read my last question, but it was in regards to finding a relationship for someone who is introverted a loner you might say.

Anyways I stumbled upon this one girl on dating site that was suggested. Profile said she was shy, simple kind of girl etc. She was cute too thought kinda young she is 18, but I figured not a big deal I am 21 not huge gap.

To get to the point I noticed she never responded yet left her skype name and in her skype status said “I need help” odd I thought so I started talking to her and asked. Finally she told me she was homeless.

This all happened today. I am pretty shocked, I was homeless before when I was younger, though it was short period of time I hated it none the less. I guess I am not sure what to do. I live in the barracks so it is not like I can just let her live here. Well she could…I think, but I don’t know her.

Having been there,I feel like I should help her, but how?
