I posted here earlier about this hot girl that approached me on the train needing help. She then basically stopped interacting with me when I didn't send her any texts and now that she's back in town as she said she would be she messaged me again because she needs a place to stay fot two days because her accomodation fell through. Looks to me like she's using me. I agreed to letting her stay out of common desency but I feel used at. I haven't got a wealth of experience with girls so I figure I'll learn from the experience of having a new girl over but should I try to fuck her or take it for what it possibly is, she actually needs help and isn't actually interested in me?

Here is my initial post:
