For the first time, she showed remorse but more so about what pain she had cause instead of for what she had done.
Guilt, not remorse. WAS's usually do feel guilty, but they feel justified. They feel they are doing what is best for them and for the LBS. They usually don't want to hurt the LBS and often are surprised the LBS is even objecting to breaking up the M. It's not uncommon to hear "but I thought this would make you happy" which is EXACTLY what my XW told me. I mean I get why they think that, it's usually the case that both spouses are unhappy in the M. But I think WAS's tend to misinterpret that as meaning that their spouse wants out of the M too, which is usually not the case.
