TS,

The way I see it, she gave you a chance during that first few weeks. You were not able to close the deal and now, unfortunately, her interest in you has waned. Maybe you were too boring or too nice or whatever it is that turns her off.

And now I think she is just too nice to ghost you completely, hoping that you take the hint and give up on your own.

Sorry if this is harsh, but dating can be like this.

You now can walk away or still pursue. Whatever it is good luck.
