I just read your thread, hope you don't mind me coming in on this. Just one thing crossed my mind when reading, you said
"I just want to reach out to her and put an end to this silly game, but I feel like it will just push her further away. She is having a very rough time at work now and I can't do my job as her husband to the full extent. This whole situation is just sad"
She is not letting you do the job you would like to be doing as her husband. I really think you are doing your job as her husband because by not cushioning her all the time you are letting her feel the consquences of her own actions. It sounds like you really want to protect her from hurt but you can't. This is the path she has chosen to take and I think she has to feel it to realise what she has got.
I hope your week with you children is improving. Use these times to show her what she is missing and that you are a fantastic Dad and that your children are as happy as they can be in that situation. I think that you will find that rewarding even if you feel you are not getting rewards from her.
