"I have decided that I am moving back into our home. If you are not happy living with me,you will be the one to leave. I am willing to stay and work on the marriage but if you are not, you should go. I have some decisions to make about our marriage, too."
So what if she gets angry? Don't be afraid of her anger. It's far better than her apathy! My H stood up to my decision to leave and it was the BEST thing he could have done for me. It let me see his strength, his resolve to do what was best for him and our family, and he earned my respect. I came home.
If he would have sat back as I see you are doing, I would have concluded nothing had or would change and I would have stayed gone.
