I have a very similar story…
Now with 12 years behind us and mid-life upon us, I can say categorically that your spouse will grow and change in ways neither she nor you could have anticipated. You will do the same.
Genes, hormones, life events will change what you want for your future and what you need in a partner. What you both want or need in your 20’s bares little resemblance to what you’ll want and need in your 50’s.
Luckily, half of us continue to grown and change where the differences are not insurmountable.
I wish you both the best of luck and hope you both grow to be part of this half.
Many of your peers will not.
