I actually did what I considered a jujitsu move @ transparency- " You know what I won't tolerate from you, If it happens you know I'll find out I'm done talking about it and wasting my time on it. If it happens you know the consequences, it's your decision."
That ain't jujitsu... you wanna see jijitsu... watch how she comes back at you with a reply when she does. As far as consequences... why should she fear them? She's crossed your boundaries numerous times in the past and you've let her get away with it.
Can you tell us what's been going on since the meltdown?
