I think your post above has a couple things I want to advise about.
1) just because your W says something, doesn't mean it's true. Remember, believe nothing they say and only half of what they do. So, of course she can't see you being together NOW. But the world of a WW is so unstable that tomorrow, next week, next month, next year, her mind could be totally different.
2) you mention about this weekend and dynamics shifting. You need to prepare yourself that this process is not fast. There is nothing you can do that will "flip a switch" in your W's mind about you. Instead, you have to think of it like a dimmer switch. Right now it may be off. Through consistent actions and 180s, you may be able to turn the light on and slowly get it to brighten. But even if you were to have the BEST day together on Saturday, it isn't going to change her mind at this point.
Because of those two things above, you need to start to detach yourself and get your own life. You can't wait and hope she changes her mind. She doesn't want you anymore as you ARE. So you take this time to make the improvements in yourself to make you s Bette friend, patent, partner, etc. once that process has been ongoing, your W will be able to see those changes and decide if she wants to be with the person you have become.
