If you've made some changes for yourself, then that's okay. Maybe you don't have any other changes to make in your life at the moment and that's okay.
As many spouses still have their MLCing spouses still living under the same roof, it is difficult dealing w/them because you are looking for them to be the same period pre bomb drop. They aren't. They revert back to teenagers and do a lot of acting out. This is where you need to dig deeper for patience and try not to mind read or "assume" what they will or will not do.
You will learn, as you walk the path, that your wife has become your roommate. She's going to go about her business and do whatever makes her happy. You will need to find your footing and this is the hardest part of living under the same roof, begin to look at her as a roommate. You will need to develop friendships outside the home and begin hobbies/interests that will not include her. I am going to suggest that you read HaWho's threads. Her h is living in the dorm room and has been there for quite a while. Another good example is ForeverYoung. He worked hard, dug deeper for patience, and it looks like they are on the road to healing.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
