Being swapped for a younger model

[ciele]

I know I am not being AIBU because I'm fuming. I'm in my early 50's and the cliche of seeing friends being traded in for younger versions is becoming rife.
Just in the last week I know of one whose wife has MS, one who now has a blonde with two young kids, the local joiner who has left 3 kids and wife.
I did ask my husband if he was swapping me soon but tbh I think he can't be bothered.
Am I being unreasonable to suggest middle aged men appreciate their middle aged wives?

Yanbu. It's horrible.

It isn't just woman in their 50s though. A male relative of mine recently left his very beautiful, mid-thirties age wife and young children, for a mid-twenties, single woman. He moved into her teeny flat instead of the nice house he was in with his wife (and which I imagine she mainly paid for, being the more successful one career-wise). The new relationship with OW has now ended, (probably as the new GF probably realised what she was signing up for; stepmother to young children, financial difficulties as the relative, who isn't great with money to begin with and has a low paid job, has a financial obligation to his children and stbx wife). Such a mess.

Sorry but not my personal experience.

If my OH had such a fragile ego that he needed buttering up by a "younger model" then good luck to him.
I am better off without such a man.

OH and I are happier than ever, it's never crossed my mind that he would "trade me in".
We have a very colourful sex life, I am fitter in in my mid 50s than I was in my 20s.
I earn more than him, work half his hours, we have a happy family fife and laugh like hyenas.
Even getting married next year after 20 odd years together.

We both have our bread buttered on both sides.

It definitely isn't all men, but some do seem to live up to the cliche (looking at you relative).

It is not just men who do this. I know several,women who have left long term partners and husbands who are now busy shagging their way through a variety of young men.
