According to the constellation, although I am an Aries girl, I still know a little about Aries boys. In my opinion, Aries men like you very sticky, and sometimes they don't even have a chance to breathe. It was because they were too sticky to stand points.
But everyone's personality is different. Just because you don't call often doesn't mean you don't like you. Try to communicate with him to see if he doesn't like calling you, and then you can adjust it slowly according to the situation.
