I am very sorry for your hurt. I’m speaking from my own experience. After over 30 years of marriage I was told that we needed to go separate ways. You really shouldn’t be surprised and if you look back closely I’m sure you will see many signs that were missed. This seems to be a common occurrence nowadays.
In my view , the idea of romantic “ forever “ love is an unrealistic proposition.
Human nature seems to work against the ideal.
My advice is plain and simple , learn how to be able to live life for yourself and no one else. It may sound selfish but we’re talking about survival here.
Realize that the circumstances of life can change dramatically and instantly.
Realize that if you can work it out , fine. If not , also fine , because during all of this you will find your inner strength.
Wishing you the best.........
