Kimmerz, I am so sorry to hear about your dog. She lives a good life and a long one w/your family. You did the right thing. In time, I'm sure, you'll get another pup for company.
I'm also sorry to hear about the cousin who is ill. Hopefully they can find a suitable transplant for her and soon.
You have finally taken off the rose colored glasses and see what your xh's behavior is like. Detachment has given you this new perspective on him. In his passive aggressive way, he's punishing your family because of the Thanksgiving rejection. He's not very bright these days and telling your daughter she would have to pay for Netflix. Well, he didn't count of his threat backfiring, i.e., no reaction out of you. One more thing he can't "lord" over you or your girls.
You've come a long way and now can see the light at the end of the tunnel. After the holidays he may very well lose interest and settle down for a while. Holidays tend to be stressors for them and they tend to come out of the woodwork and do stupid stuff. I hope and pray he's done his damage by cancelling the Netflix and will crawl back into his hole for the rest of the holiday season.
Hang in there. We still have a chair for you on the curb so that you can sit w/the rest of us and watch the parade of mlcing spouses charge by.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
