How will you proceed forward as a couple based on the stars? Um, I don’t know. I don’t gain insight into the future… I just know a fair amount about the stereotypical star signs. So. Um. With that said.
I do think there’s a warning flag between you two. I mean, generally people with a Pisces Moon identify more as Pisces than their Sun Sign, so it’s very possible you don’t resonate strongly with Sagittarius characteristics. HOWEVER. The Sagittarius and Scorpio mix is frightful. I think this combination is potentially horrific. They both tend to want to do things their own way, don’t like to be told what to do, and have a tendency to boss people around. So. I’m sure you could see why that might be problematic? However. Your moon IS in Pisces— and many Lunar Pisces don’t identify with their sun signs strongly.
The typical sun sign Pisces-Sag match also is generally incompatible.
However, I want you to consider this. If it is true that you identify more strongly as a Pisces, that Sagittarius in you might act like a bit of a special spark. You know, make you a bit of a firecracker. Pisces might drown out the Sagittarius, but it’d still be there— in which case, I think you two might be rather compatible.
I know this reply isn’t very helpful. I’m honestly inclined to say it has a chance of being horrible, or really quite nice.
