Asking for a friend

How much time do you think is too much time apart?

What is your minimum? What is your max? How much time to you think is healthy to go without seeing a partner?

I'm so used to clingy/dependent relationships that my current partner seems to be quite independent, and I'm not used to the amount of time he can go without speaking or seeing me. I'm not sure if he is somewhat avoidant of commitment or if I am too clingy, or if both things are true at the same time.
