Good to see you posting, Shaky. And congratulations on making the changes in yourself. Remember that these changes are for you and have no expectations that they will make your W "come back to you."
Your W, when asked, says she does not know why she is not "attracted" to you. This is important.
First, you may have read here that we should believe none of what the WAS says and only 50% of what they do. While this is true especially in LRT (last resort technique), this comes with caveats...
There are certain things, such as them asking for space, that we really should take at face value.
Anything that you do could be seen as pressure. That does not mean you do nothing. It simply means that you have no control over how she takes what you do. So do what you do, for you to be better. Keep what is good, become an even better version of yourself, and stop doing what isn't working.
We cannot mind read, so there is no way for you to know what your W might find attractive... what might attract her to you and fuel that passion... unless she tells you, and she states she does not know...
Stay focused on you, be the best person you can be, and have patience...
