Sorry about going to the house and seeing that. That would upset me too. Hopefully that is the last time you will have to go there. I wish I could get a pic or video of our dog :-(.
Anyway, if I were in your situation, I would ignore it to be honest. I tell my closest friends and family everything but keep details vague to the 'drama starters' even if they are friends. And, of course, I don't talk to her friends about the situation.
I hope being physically separated makes things a bit easier for you.. it does for me.
