Saturn (reality) and Neptune (fantasy) are making a supportive connection that will last until January 4th. Saturn in Libra means relationship responsibilities and realities. Neptune in Aquarius gives us a very manageable shot of idealism while it trines Saturn.
The first thing that springs to mind? Make your relationship dreams a reality. This is a possibility right now if you approach your dreams in a balanced (Libra) way. Other things to do with this energy: make peace, reach a mutual understanding, end a relationship in the least painful way possible.
Aquarius and Libra are Air signs so the feel of this aspect is reasonable and calm. It's rare that Neptune idealism is supported by Saturn. Plus, Venus (Libra's ruler) is in Aquarius. Although she's not aspecting Neptune or Saturn, Venus's presence in this detached sign makes it easy to step back and chill.
The takeaway message is this: let it go. You'll either get what you want by giving someone their space or you'll find it very easy to cut ties. If you have planets between 26-28 degrees Aquarius or Libra this aspect will be especially strong for you.
