W is angrier after my 180's - time + consistency

[MrBond]

"I also realize that my actions that precipitated her A were what created the environment that then landed us where we are today."

Again, remember it's a two way street. Your W wasn't exactly walking on water. On top of all that, there is never a good "reason" to have an A. No matter how bad things get, you work it out and not call in a substitute.

"However, part of me wonders how convenient would it then be for her to hook up in the privacy of an apartment if that was her motive."

You know of course that's a real possibility. Part of her might want to "experiment" with other guys especially since she had an EA. You have to face that possibility now so that if it ever became a reality, you are able to face it without fear. Think of the worst case scenario for you and go through all the emotions now. It will help you to become better equipped for things as they pop up.
