Why did he just disappear?

So I met off a guy off reddit and me and him are both single parents. we agreed to be friends. he lives in Virginia for the Navy and I live in Oregon so I wasn't expecting anything romantic and i told him. so as a few weeks go by we talk and I help him with his daughter like advice wise. he then brings up to me he starting to catch feelings and I sorta like him but I just say to stay friends because long distance wouldn't work. we continue talking & joking whatever. he then says one night to me he loves me ! caught me off guard. he didn't say it to his ex til a year later he said. so he was just hopeful that we would be together I think it might very ruined our friendship now? He went 3 days without talking then said he was going through things and like now he hadn't messaged me for almost 2 weeks now. i last messaged him and no response he did watch my snapchat story once. but I'm confused why he disappeared. we agreed to be friends. should I just delete him now from My life?
