Sleeper-I agree with what you said about not doing anything for her. It's hard, but I've been doing. Two nights ago she called and wanted me to take the kids a bit earlier than usual because she had an appointment. I told her that I couldn't because I had an appointment as well. She kept talking about how she would just have to take the kids with her and she didn't want to do that. But I didn't give in. Even though I want to spend every moment that I can with the kids, I can't be at her beck and call.
Christmas was hard. It was the first Christmas eve I've spend alone in over fifteen years. Christmas day we gave the kids their presents and then I brought the kids to my parents. They spent the night and I brought them back the following day. I did not take the dogs out for her, did not straighten up, did not shovel the driveway. I said goodbye to the kids and went home.
She's called a couple times and I answer her questions, but don't elaborate or have a longer discussion. Today she called and was extremely snippy, but I just ignored it and went about my day. Unless I have the kids, I do not answer when she calls but call her back later.
