the only thing I wonder is if because I wasn't more direct or didn't take more of a stand earlier, if it contributed to the A escalating to what it is now.
The short answer is "no". Once it started happening you couldn't do anything to prevent it. All you could do is make it worse by trying to intervene. They would have worked around you and just gone deeper underground.
When W is working late, it would be great if you can figure out a way not to be home waiting for her. Is it possible for you to make your own plans after work and go out and have your own fun?
