I have discussed this with a few of my friends including a married couple who have been together for years and they all agree that cutting the wig was way out of line. Unless you are in a Dominant submissive relationship then this isn't how it should be and I suggest telling her that she went too far and talking about it.
Yes you did set a series of rules with her and yes you broke one of those rules. Tell me this though when you were setting the rules did you agree that if you broke one of those rules she would destroy your stuff, and what happens if she breaks a rule?
Also if she really loved you she would understand that you need to do this. She should love you and want you to be happy and she should understand that people make mistakes sometimes. It's not like you cheated on her or anything like that and its not something permanent and its not even unmanly for a guy to shave his legs. Male swimmers do it all the time. Marriage is about compromise and it has to work both ways or it doesn't work at all.
Sounds like the two of you need to have a serious heart to heart about what your relationship is really about.
