With progressions, things
do have a way of occuring as they must, with the transits providing the necessary push..
In my husband's case, the progressions appear to have prolonged his life.
Pressure may have otherwise taken its toll on him.
In my son's case and with hindsight, his divorce
was for the best. It made him concentrate on himself and pick up the pieces of his own life again (tr. Uranus/Aquarius influence?). With trauma and difficulty he got through the transits Saturn-Pluto to his natal Moon-Pluto in 7th. He went back to his 'first love'....the Neptune-M.C. in Sagittarius helping profession. He is now a fully qualified and specialised First Aid instructor, providing instruction for large professional businesses.
Ummmmm....I've got 2 daughters as well, if you're interested.
