I was in a similar position to you Mrs Expo
I had been with my husband for 30 years, had 3 adult children, a lovely life and home
DC were all settled with careers and homes of their own,
We had our good health and a lovely group of friends
Then, he sold the family business, retired and practically gave up
He changed from being this dynamic busy man to someone who just wanted to plod day to day, doing nothing
We had talked of travelling, downsizing the home, weekends away and spending more time in our apartment on the coast
This all changed, he told me quite frankly a few months after retiring that he didn't want to do any of the above and was quite happy for us to stay in the family home and I could do all these things on my own, he was happy for me to do this
He became quite controlling in lots of areas where he had never shown interest before i.e. Weekly food shop (it was his goal to get it to the absolute minimum) the cheap crap he bought, the out of date stuff
He complained when I bought myself something
He wouldn't go out for meals unless it was somewhere that was doing a cheap deal (not a problem to me) but it became some sort of quest to find the most terrible place selling terrible food all to save money
This then turned into a mission
He started to buy his clothes from charity shops, again nothing at all wrong in that, I volunteer in one and its lovely,, but a man who used to have suits made, a Hugo Boss dresser who then looked like some scruff was so out of character
All this and he is only 57
I couldn't take anymore and after 18 months I left, he went to pieces, we talked things through for a couple of months and we got back together again but this all changed within a few weeks. He became morose again, still controlling and emotionally distant so last summer we parted for good
I miss my family life, my old fulfilling life and the man I married like crazy, but he has changed. My family unit is fractured and for that I am so sad
I now live in a new home, have new friends, new hobbies and am getting there with counselling
My family and friends have been great throughout
Guess what though - just after Christmas he met someone new online, sold the family home and moved 100's of miles away to be with her all within 10 weeks
The shock is unbelievable, this new person will now be getting the man I thought I was going to grow old with, a different version admittedly, I accept that this has happened but I will never understand how a person can change overnight
