Not to derail the thread to much but the answer is yes and yes. On the one hand you do want to do those things that you always talked about. It shows that you are changing and may even make her wonder if it was her the one that was holding you back.

You also want to be unpredictable, I think WAW's for all their bravado and stubbornness usually want to believe that should they change their mind they can always come back (no matter how atrocious their behavior). This way they have a safety net, and if their new lifestyle of love doesn't pan out then they can always return. Being dependable ironically gives her the security to venture out and leave.

If you were a pushover to begin with and this made you unattractive it'll just make things worse. So changing it up will let her know that her safety net may be here today, and gone tomorrow. Which puts you in a better position where she to start having second doubts.
