Excerpt from my latest Sasstrology article (please leave comments on the Sasstrology site):
"Saturn’s recent ingress into Sagittarius brings a fresh awareness of its effect on your relationships. While Saturn transits can present challenges for your love life, this planet also crystallizes things. Read on for an overview of general pointers to deal with Saturn aspects to your relationship planets. Note that “relationship planets” refers to your Venus and Mars, but also any natal planets that rule your 1st or 7th House cusps, or are located in your 1st, 4th, 5th, 7th or 8th Houses. Also, Saturn moving into these houses, or making a hard aspect to your North or South Nodes, can impact your love life. This information is not sign specific, but I wrote this article about Saturn in Sag’s impact on the Fire signs, and this article on what it will do for the Mutable signs."
