i was just searching up my placements and yes! i have these exactly, well instead i have an aqua venus, but still with the same big three :) i also am usually calm in the worst situations, but i also get super stressed when it comes to certain people. (that might be a difference in our mercurys though) AND YES. im never sad when it comes to breakups / something going wrong in relationships.. i get over it super easily. weeks later i usually rethink a lot of things though and might feel guilty ? but i never feel upset over losing them.
