Contacted ex after two weeks. Afraid he’s moving on

So. I have contacted my ex just the other day, which was the two week mark of me issuing the no contact rule. I messaged him on Facebook to simply recognize my wrong doing in the relationship, and understanding how he must of felt. I also stated that I was doing this not in hopes to get him back, but that I am sorry for all wrong doings. He hasn’t responded. Which, doesn’t surprise me. Anyways, I deleted him off my Facebook and Snapchat, but I’m still able to view pictures of his since his pictures are public. Today, he deleted all of the pictures of us and the ones he uploaded. I’m scared to death that this validates he is moving on. I mean, when he broke up with me I had deleted all of our pictures immediately because I didn’t want the break up haunting me. I’m keeping my distance now and am not going to contact him for at least a month. I asked him three days after we broke up when we can get each other’s stuff back. He hasn’t responded. I’m really wondering what is going on in his head. HELP!
