Right step back a minute there mate, 'punish'? Your thinking about this completely wrong, you may have had the initial attraction when you were the 'alpha' in work, but now she's got you, much like a child that's gotten the toy they envied that they now no longer want to play with because they've gotten it. Just back off her a bit, go do your own thing, go out with the lads, talk to people etc. If she's interested in you let her come to you, and if she doesn't? Then fuck it your better off with somebody who shows a bit more interest.
