Because I want to know what she's up to, I guess? Because I feel I can use this information when interacting with her? Because I miss her? I doubt have a good enough reason, but I feel a very strong resistance to the idea of blocking her FB and Instagram. How would it help me to bust that D if I did?
It will help you detach. As you said, your PMA crashes when you do take a peek. For me, I stay the hell away from anything to do with Ms. Wonka and her OW. Although I have seen a picture or two. Gag!
Staying away from FB isn't going to 'bust a D' of and by itself. It is your 180s and consistent changes that hopefully would bust a D. Focus on this part and forget about FB!
Your response to W's query about her video was a doozy. C'mon...where's the take charge Mozza??
