I pray she shows her true colours and he realises he is throwing away a M of 33 years.
She will eventually. In fact she sounds like she already is, but as long as he hasn't "lost" you, he won't see it. And he might not until you are divorced unfortunately. Then he gets to deal with her all on his own, and it will be ugly.
In my first bout of this, I absolutely, positively knew she'd be back one day. I didn't expect it so soon (2.5 years), but I just knew it. And I was right. Now, I'm not so sure, but then again, I'm not sure I would want her back again. I was able to get over it the first time by thinking it was a crisis and she wasn't herself. Now, I'm starting to wonder if this is her self, and I'd have to walk on egg shells the rest of my life to keep from MLC triggering again. But, like many have said, she didn't finish her crisis the first time, so who knows.
