I miss him so much and I'm confused

My relationship broke up about a week ago. He wasn't angry... just really sad. He said he was never really in our relationship and couldn't love me. That combined with our recent arguments lead to the break up... he promised we'd always be friends and he's there for me if I needed him. However since the breakup I haven't spoken to him and he hasn't reached out to me. I feel like I need space and I'm not sure I can be friends with him at this point. I really want him back and I want him to be my partner again. I've been doing a lot of reading online and one of the best ways to get an ex back is through a no contact rule. So I'm going to not contact him for 30 days ideally. However I miss him so much it hurts. I miss talking to him all day long and texting each other all the random and mundane things that happen in our lives. I miss nerding out on our favourite interests together. I miss being his sounding board for his story ideas. And it hurts to think that he'll never want to kiss, cuddle or type hearts to me again. I want to talk to him so badly that I find myself obsessively staring at his online status and I can't stop thinking about him. There are times where I'm not sure if I miss him as my friend or my boyfriend or perhaps both. I don't know if I should reach out or not and if it will ruin my chances of getting him back
