Do not wait around for her, in any shape or form. She might come around, and then again she might not. I am not saying you should start dating or anything, but you do have to get on with your life.
Try to remove any memories from the line of sight (photographs, keepsakes,...) because they set you back a little each time you look at them.
And then continue with rebuilding your life without your W. As you have discovered it is futile to reason with your kids, so you must speak with actions. They will get it with time (hopefully)...
Go out, hang out with people, go hiking, bond with nature.
