Advice for 59yr old whose husband just left after 22yrs

Hi everyone- as the title says - I need some advice after my husband just left me after 22yrs together… I’m reeling from the shock still - he told me on our wedding anniversary (2nd Nov) and I’m still struggling to make sense of it all… Obviously my world and where I thought we were heading has been turned upside down…I’m not looking for relationship advice - he’s made his mind up - (without my knowledge or any discussion) and I just don’t know where to start with piecing my life back together…every single one of our friends and family are as shocked as I am and can’t believe this is happening… I’m a young 59 yr old and have just finished my MSc in Paramedicine (I’m in the U.K.) - but my thoughts of doing this now are gone as it was part of our plan together… So much of what I thought was going to happen is now up in the air.

1. Has anyone experience of any of this?
2. What did they do to find clarity in their lives?
3. How did they move on with their lives?
4. I feel so late in life to be starting anew with everything any advice gratefully received…
