Is he giving hints that he no longer wants to talk to me?

So I’m talking with this guy for months now. We met online and have so many things and beliefs in common. He is super respectful (unless he is teasing me 😂), and has shown so much interest in me. The fact that we invest so much time every single day talking, to me it means something. Since we have started talking (early February), I felt a connection. And the fact that there hasn’t been a single day that we haven’t said at least a “hi” surely means something.

He usually texts first, I get a good morning text every single day (some days I get it on midday because he wakes up late sometimes but I guess better late than nothing haha). The fact that I’m the first thing he thinks about when he wakes up makes all of this feel so special.

It’s been 3-4 days now, our conversations are limited. I feel like we ran out of things to say, and that’s not good. I still get my good morning and good night texts, and kisses, and he is interested to know how I am and what I’m doing. But the texts are not continuous. For example he’ll text me, I’ll reply after 20 min and he’ll reply after 1-2hrs. He sometimes says that he doesn’t get notifications of my texts immediately (which happens with me too sometimes, I think it’s an instagram problem), or that he thought he replied (happened only 1-2 times), or that his network is slow. Yet, he shows interest in our conversation, he is not monotonous. He answers with full sentences, adds exclamation points, generally shows excitement in the conversation.

Me on the other hand, I’m not the exclamation mark type of person, I may use an emoji but with him kinda rarely. I’m the type of person that instead of “Nice!!!” I’ll type “Niceeee”. I’m not sure how he sees it. I don’t want him to think that I’m bored of him. I crave talking to him, but I don’t show it. I don’t want too seem too excited on the other hand.

How can I show him some excitement without being too much? It’s a pity being so excited talking to him but not showing it. I don’t want to make him bored of me, but it seems like I am...
