When you're missing someone and you want to tell them but then you realize that they don't care anymore is the worst feeling to experience to be honest.

It’s like being at a zoo and wanting to pet the animal but you’re blocked by the barriers, does that make sense?

You just don’t miss the person but I think you miss everything that has to do with them. You'll miss their voice a lot, you'll miss the smell of them, you'll obviously miss talking to them and more. 

Everything changes once they’re gone. Like something will happen and you’d usually run and tell them, but then you’re like, “Oh wait, they don’t care.” 

Everything also reminds you of them which just adds to it. It’s virtually impossible to fully disengage yourself from them especially when you're so fucking attached to them before because they once meant the world to you.
