It seems to me that she is either playing hard to get (which would be a dumb move on her part), or she is horrible when it comes to using the correct words to convey her feelings and thoughts.

I've given up on that question. In the 2010s so many ladies react poorly to that question. We've been hanging out several days a week, texting every day, sleeping together, but I ask that question and it's a "no". Sometimes it's the opposite though and they get super excited as if I just proposed.
