As a whole, both of them get along but do not have much time to get to know each other. This whole game might be too much for them because when they are left alone together they will realize that they actually don't know each other well enough.
The Aries woman is willful and she rarely bends knee to anyone except herself and her own wishes. But this does not mean that she would not change in the name of love or true love.
She has a relatively calm disposition, at least up until the moment when everyone ignores her. She is plenty impulsive, one of the favorite traits of the Sagittarius man.
He, in turn, is spontaneous, which perfectly suits her impulsiveness. He likes to learn new things, to explore and will succeed in making her passionate about the new and unexplored. At times, the Sagittarius man has an adventurous spirit. Sometimes he demonstrates fickleness.
If problems were to arise between them, they would most likely be due to the fact that they don't know each other that well. They like each other, they get along, but the part where they have to get to know the other person troubles them to some extent. They do not seem to spend enough time doing this.
Their adventurous spirit and desire for joyous times will play a role in all of their activities, including the sexual aspect. They like being different and showing each other new things - this make the adventure even greater.
If they are able to become familiar with each other well, they may decide that they are meant to be. In general, they truly complement each other or rather, are completely the same in some aspects.
The Aries woman will at times become agitated by his philosophical reflections. The Sagittarius man will think that she is too jealous but even so things may lead to more serious relations.
That which will be most lacking in their relationship is calm, but if they remain together long enough, sooner or later they will feel it.
