In a couple, Mars in Aries brings abundant energy that moves quickly from idea to action and voices anger head-on. They enjoy varied physical activities that let them act without being tied to constant repetition.
When there is something to be done, they are usually among the first to get up and start. The impulse comes quickly, and they would rather try than linger too long in deliberation.
If something bothers them, they say so directly. They may speak without weighing their words enough, but they usually calm down once they have voiced their discomfort. In this description, anger tends to be intense and brief, rather than a resentment that drags on.
The saying “After the storm comes the calm” captures that sequence, although the calm that follows doesn’t erase the effect of what was said.
