I have been talking to this girl for a couple of days on Tinder. She sent me today "Why are you on tinder?" In which I responded that I wasn't entirely sure and was open for anything and why she was on tinder. She then asked "Do you want to be my fwb??🙃"

I'm not really sure if she's just joking or testing me haha. I mean I would be interested if she's serious I think just based on hear pictures but haven't even met her in real life. What is a good way to go about it?
