In my opinion, it seems that your wife is upset because you decided to lay down a boundary by withdrawing from her drama.I believe that the divorce papers were her way of telling you 'fine u don't want to talk to me, now you REALLY WILL REGRET IT!!!'
Sounds childish but it doesn't surprise me. This sounds EXACTLY like a conversation I had with my ex.They want you far away but not TOO far away.
So, you excited for the upcoming college football season yet? Your Canes got a big test early in the season against the Buckeyes. Should be a good one.
Me on the other hand, I've been waiting for this season for a LONG time. Should be fun.
