I'm new and in my own predicament, but I'm also up late and want you to know I read your post.
Right now do nothing. Just sleep on the couch tonight, try to rest. Try to take care of you. Do not do any more begging or groveling. It's not becoming of you and it's not going to change her mind. There is an OW in my situation so I'm stuck similar to where you are in that I can't work on anything regarding the marriage until the 3rd party is removed from my marriage. But we can work on ourselves. I've taken this time that my H is 'thinking about what he wants' to work on strengthening myself. You need to take care of you and do the same. Try to sleep. Make sure you eat tomorrow. Give your kids big hugs tomorrow and try to have a happy moment with them. I'm sure you will get more feedback in the morning.
