HELP! I am really confused with my friend

So sorry if this will be a long post. I really need your HELP.So I have this Texan friend that I met through a mutual interest. We are talking thru Instagram DM. We talk about stuffs we like and everything. Random thoughts.Until I was lonely the other week with no one to talk to. All my friends are busy with their commitments or work. And it happens this guy was online. I told him I had no one to talk to, so he was good enough to listen for me. We also shared deep talks. Of course, those deep talks will make you really know each one. I told him about my childhood, past lovers and other things. And he told me things bout his life too.The other day, we were chatting, began with usual talks then he started saying dirty stuffs. Of course, I am up for dirty talks so I played too. After like an hour, I told him I do really need to go. I hate lying, so I told him I am about to go workout since I am trying to be enlisted in service. And he be like 'aww you're leaving :('And by the way we call each other baby.It happens I was really busy the next day and he sent me a message that he was worried why I didn't talk to him all day. So i apologized and explained.Yesterday I went exploring places went on a park, malling, lots of stuff, I haven't talked to him that day.I am a really busy person with lots of clients and I talk to my friends whenever I have the time. And now he sent me a message and our convo be likeWHY HAVEN'T YOU TALKED TO ME TODAY THOUGH!!?Me: I am busyToo busy for me?Me: What? Why?I'm just saying... :/Me: Don't see it the wrong way. But we just happen to talk about stuffs may it be dirty or flirty or about anything.Yeah and that's good. No?Me: Yes. That's good :)And that doesn't mean we can't talk a lot does it? Does it?Me: We both have commitments and things to do daily, it just happens I can't talk almost constantly.and now i don't what is happening! I was just being playful and I really don't know what went through him. We're not dating, we are both too far from each one to casually see each other.Did I led him on? Was I not aware of what I'm doing? Or there was something I did for him to be like that?Aaaaaargh!!! I really don't know what is happening!!!
