I miss him

I get points where I miss him so much that it hurts. It's like there's a pain in my chest and it feels so overwhelming that all I wanna do is cry. He was part of my life and now he's not. I miss hugging him, kissing him, holding his hand. Believe me though I don't want to go back, we ended for a reason and I'd never go back to him. But I still miss him. Certain parts in the day I start feeling sad. And although I don't want to hear from him again because it's for the best, I do still look at my phone expecting to see a message from him. Especially in the mornings when he'd used to say good morning to me. It sounds silly, I know I'm not gonna see a message from him, but I've been so used to seeing it. Will I stop looking for this? Will I stop looking for his car when I'm out? Will I stop missing him? It's been 5 days since we split, there's just certain times in the day where I miss him so so much
