being emotionally dependent on someone who doesn't want you is horrible ;-;

A few months ago (more specifically 7) I met a boy in a WhatsApp group to get stickers and we started talking after a while, but as the months went by I ended up creating a dependence on him to the point of not being able to stay a day Without him, I was already getting sick of it and I didn't know what to do, it's as if he was my boyfriend even though I knew that would never be possible. We still talk but it's like every day we move away from each other until we reach the point where we stop talking completely. He doesn't treat me badly but he also doesn't want to have any kind of relationship so I'm not going to force it, I think the best thing to do is just keep it up as long as possible.
