All I can recommend in this situation is to be patient.

Maybe ask W to move to a spare bedroom? If she won't and you really can't handle the same bed then you go to a different room.

As hard as it is, being in the same house let's her see your changes. If you keep up the 180s of the stuff she doesn't like, and keep GAL, she'll see it.

If she really isn't all the way to lesbian on the spectrum of sexuality and she is even a little interested in you anymore, that may give you a shot.

Sorry, that's all I've got.

D talk has slowed, a lot.
Gradually working on things together. Still separate bedrooms.
Slow and Steady wins the race.
