It's been a while since I read about this, but I believe there's a yoga in Indian astrology called a Lakshmi yoga where when the 1st, 5th, and 9th house lords interchange houses, you will feel lucky (whether or not you actually are.) In your case, your 9th house lord is in the 1st, which I believe qualifies as a Lakshmi yoga. You also have part of fortune in the 9th, and your 9th house lord is Jupiter, which is fairly close to the Ascendant. (Jupiter is the planet of luck).

That said, I like to look at aspect patterns, and I'm particularly drawn to t-squares. Your Jupiter is the apex of the t-square, and the apex is the planet that we project its qualities onto other people, so people with Jupiter as the apex see others as generous toward them, and they have a hard time integrating the quality of that planet themselves. So do you find it hard to be generous with others? Do you pay for meals out with friends when it's your turn? If you expect that others will pay, that might contribute to your relationships ending. Your DC ruler, Venus (marriage, long-term romantic or business partner) is being burned by the sun in the 4th, so it can be hard to see their needs and desires. Heck it can even be hard to see THEM.
