I think I messed it up??

I went on a date with a guy I was talking to for months. We finally met a few weeks ago. He mentioned he wanted to hang out again three different times but he said “sometime” and “in the future”. This is our last interaction. I said what I said because when he would talk before we met he said: marry me! And I was like haha you’re joking and he would say: we’ll have to meet first. It’s like I praise him once and he says it again which you can see in the text. We’re just joking and I do like him. He’s 26 and I’m 22. I texted him back at 2:35pm the next day I was busy with my sister. He views my snapchat stories still but doesn’t reply. I wonder if he’s hurt or just done with me. If we didn’t text for a day or two I would send him a meme which is where he said I could add him on Facebook. And he said yay!!!! Then what happened next is in the convo. So should I tag him in a meme to break the ice or just leave it at that. I feel bad when I don’t text back but I am busy!!
