or she wasn't interested in the first place,
Well:
I even asked if we could go out on our own to have a coffee together, and she accepted, but asked for some time to sort things out on her life
So all I am hearing/seeing there is a no. You asked her out and turned you down and you have not heard from her in a month
It is pretty clear to me she isn’t interested.
Did you ghost her? Does that mattter?
