Do i have a fear of being alonephobia?

Hello, im 16 and i have a boyfriend. We have been together for over a year now and i belive that i might be developing the Fear of being alone. I feel like i have to be with him all the time. I know i shouldnt do, and i should be giving myself and him space.
However when we have time apart, like a day apart i feel intence sadness and even start crying and some point. I cant enjoy my time alone sometimes because im not with him. I know its not that much of a big deal, but its whenever we arent together, i feel down unless im destracted or at school. I have looked online for the defination and syptoms of this fear, but i need to know from people who have had this experience.

Thankyou
