Right now you need to step back from all of this craziness and calm down.
Your first step is to gain your footing and get to a place of peace, which in and of itself will be very difficult right now. You also need to be strong for YOU and YOUR kids.
I will post a little more later BUT for now, keep quite and do not respond or reach out to your H. DO NOTHING.
Can you also do me a favor and let me know what complaints YOUR H had about you and the R?
God Bless, Eric
