Yeah, if I were you, I'd figure out a way to keep in touch with something neutral and fun in the middle, like your writing dates, but avoid the at each other's houses, since she does not seem to want that. Renegotiate the relationship. I've had to do that a couple of times, and some folks fall away, and some, you get through to another stage of the relationship eventually.

I would also cultivate a new friend. too.
