Ask *nikki* 
Seriously though, some of my female friends have said too nice was just that. They liked a bit of rough with the smooth. Ever hear of "treat 'em mean, keep 'em keen". They seem to enjoy not knowing exactly where they stand, gives 'em something to worry about.
I treat my ex like shite and she still wants more (To the ladies out there I am not a bastard and have told her I don't want anything more to do with her, but I suspect she may be a bunny boiler).
Now I found a new bird who is everything I want and am finding it hard to be cool. Odd but also slightly fun...
