Will I marry this man
After a very cursory glance at the chart, I see you are appropriately, represented by 6 degrees Cancer rising: the Moon. He is represented by Saturn. (He is much older than you?)
His significator is in your first house, which is a very promising sign. And your significators, the Moon and Saturn, are coming to a sextile, which is a good aspect. Furthermore, your moon is in its exaltation sign of Taurus, which I interpret to mean you are more than ready to marry him. Also your Moon at 25 Taurus is in the degree of "hangings and beheadings" which in a love chart, might mean you've "lost your head" over him.
The only negative thing is that his Significator of Saturn is in its detriment, meaning it's in a weakend state, and it's about to change signs.
However, I'm not sure if that means he'll change his mind about getting married or not.
I'd have to give it a tentative "yes" for now. (But keep us informed as to what really happens.) With Saturn being so weakened, that might not bode well.
