I think highly of the word friend or am i just apathetic little bitch?

I have someone who i always talk to for about a year now or more, i like being with her but if someone gonna ask me "is she your friend?", i might say "yes" because we have been talking for a year now, but to me i feel like wanting to say "no" because i don't feel something new if she's there or not. Its like she is someone i usually talk with, but i only gave her a piece of me. Which is kinda stupid of me, i dont understand how people can say they are friend with someone even though they only talk for 3 weeks or less. I would likely to say to someone they are my friend, if im comfortably talk with everything, like they Pierce through me. They can see everything i want to hide. I dont understand.

Im probably the problem lmao
But i don't like saying they are my friend feels like stupid title that i want to say to someone without feeling awkward or anything
