Just keep looking after you. Over time you'll worry less about what and why he's doing stuff and just get on with being you. I find it easier to just tick the crazy box and move on. Don't get me wrong I have bad day when I'm consumed by what he's doing.....but I try to minimise these days and do something nice for me.
You've got a great list of things to keep you going. Remember, your kids need you. Make yourself happy and they will follow. Be there for them for anything they need but don't be consumed by them either....it won't serve you well.
