What he said.

It hurts really bad, knowing that she is doing these things, and has no regard for me or how I feel about what she is doing.

If she didn't care, she wouldn't be trying to get a reaction out of you. She is not completely detached either. Not that that makes a difference in what you need to focus on, just saying.

Focus on now. Take it one step at a time. Enjoy your Christmas and try not to worry about the other crap.
