How do I know if things are going well with this girl I'm texting?

So I met this trans girl on a LGBT dating app and she asked for my number and said "I hope you're serious about this because I'm tired of games" (or something along those lines). Anyways, I gave her my number and we started texting back and forth. Eventually she says that she'll text me later because she has to do something. Then she asks if I have any money I can give her and when I told her that I didn't she just said "That's okay no problem" and left it at that. I looked at her profile and it said she is in an open relationship, but when I asked her if she was single she said she is. So am I being played? Should I ask her about her "open relationship" status or something? And how do I know if things are going well?
