I'm hoping he'll make it through this too, but I'm preparing for the worst. Time will tell, but I'm not too optimistic right now. Trying to stay positive.
As for the interaction w/the X, I wanted to make sure that I set up boundaries w/her as to what I'd stand for and what I won't. Her trying to manipulate our D isn't a trend I want to continue.
However, I can't stop what she does nor will I try. But what I will do - and did - was to make sure she knew I saw through her rouse and would not be a willing participant.
