"There were a couple of triggers going on, but this definitely is quite a turn from her asking me to move in, saying she thought we don't need MC, telling me how much I have changed, and that we can work through anything. "
This was the issue. It took BOTH of you to get to this point. If she doesn't want to go to MC, then she will never understand that and always look to YOU as being the person with the keys to making her happy. It doesn't work that way. M is a give and take. Unfortunately she didn't learn that.
I would definitely NOT have said you were Piecing since she took no personal responsibility to making your M work. Sorry to hear that.
