Guys, I’m afraid I just killed his interest. Can I fix this or am I better off just moving on?

I met this guy on Facebook dating about a month ago, we hit it off and I was (still am) really liking him. I’m 40, he’s 42. Yesterday afternoon I texted him something and I meant it to be playful, but I don’t think he understood that I was kidding. He was at work and I asked him to text me when he got off. He said he would try but not to be mad if he forgets (I don’t get mad about that). So then I basically texted him “shame shame if you forget about me 😜” which I included that emoji and a few others so that he would know that I was kidding, then I told him “btw I’m only kidding in case you couldn’t tell”. I haven’t heard from him since. I’ve tried texting him last night before bed to ensure he knew it was just a joke and this morning and he has not answered me at all. And this is the same guy who’s been texting me “good morning beautiful” every day for the last month now all of a sudden as of yesterday, nothing (I sent the good morning texts also and I sent one about 3 hours ago. no response), he’s not answering my texts yet he’s posted on Facebook since then. Am I wrong for feeling hurt or am I overreacting?

Can I fix this or am I better off finding another guy? I swear I was only kidding!

So after posting this, I got a text from him basically saying “I need space. I’ll call/text you when I’m back on track”. Translation: I’m not sure I want to continue the relationship. Moving on it is.
