I don't know. I know I went through something similiar right before my W moved out, and then a week later she met me to give me back my SS card, and she brought up OM and then asked if I had filed yet, and I told her to do it.
So it wasn't the same exactly, but I was very angry even if I didn't yell or anything, and I felt the betrayal, disrespect, and so on, and I felt like I had to give up on the M just to respect myself.
