Before this, I honestly would have said our marriage was darn near perfect. He has said himself he was "blissfully happy"
In the very recent months he started working a lot, not coming home, burying himself in work and avoiding home life.
He had 3 friends his age die last year plus his grandfather. I've read the death of peers is a trigger for MLC. He has said word for word a lot of the things I've read about in the surviving your husband's mid life crisis book.
