WR, There's nothing you can do to make your h's life better. He's the only one that can do that. It's a Wonderful Life is an all time classic and when your son told his father what he was watching, it brought back some memories that he didn't want to deal with.
I'm glad you sent the text to SIL and wished her a Merry Christmas. By doing so, it shows that you are a compassionate woman who still wishes the best for all.
As for your h taking your photos off FB, this is very typical behavior...don't worry about it. He's having a very bad temper tantrum and eventually, those photos may show up again. He's lashing out and knows you are checking his FB page and this is the only way that he can hurt you right now. Leave it be. He'll get over it in time and if he doesn't...shame on him.
Enjoy your week. Be kind to yourself and take some time to pamper yourself as well. You've earned it!
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.
