I miss him like crazy already!?

To start off, this isn't really a question, but again it kind of is. Anyways I had a guy friend who I was really close with we could talk to each other about anything! We also talked everyday. (He lives in a different town by the way) We ended up starting to really like each other and dated, but decided to end things and continue to have just a thing. It's a long story why. Anyways, we continued to have our "thing", but I started to feel as if we were not as close anymore like we didn't talk as much and I decided that we shouldn't talk anymore not just for that reason but also other reasons too. I told him we shouldn't talk anymore because maybe if we don't talk for sometime that eventually when we do talk again we can hopefully become close again if that makes any sense. I just also need that right now is to not have to worry about him right now. I told him all of this too over text..yeah I know over text is shady, but he doesn't have calling on his phone and he lives like 45 minutes away. I told him all this though like how he's been such a good friend and that it's probably best to not talk for a bit and he never responded...I was like cool. So now I'm just giving him his space and time to be with his friends but I really miss him and it's only been like 3 days. We were so close and I ended all that. I feel like ****. I can't stop thinking about this either. What should I do?
