My thoughts go out to you mate. You've got a lot of thinking to do so going dark, IMO, is a good idea. Also, don't forget to GAL and think about yourself. Treat yourself to something and forget about this mess for a bit.
Although I agree that it's disrespectful to the most. I also think she is acting out of anger at the fact that you are taking control of the situation. This FB sh@t is nothing more than her trying to get to you so don't let her. Stick with your plan and be strong mate. You've been doing great and guess what? You are getting a reaction. IMO, it's still too early to tell where it's going.
