I don't understand, Is he interested in me, passing time with me, or playing with my feelings?

A few days ago, I met a guy on Hinge. He is in the merchant navy and is 21. He sent me a "Hi." I replied to him, and then he sent me a copy-pasted line. I confronted him, asking where he copied this line from, lol. His reaction was like, "πŸ˜… Teach me then.".
He replies to me quickly. When I don't know what to say, he asks me. That's how our convo works, lol. We both are extroverts, but I don't know why he texts carefully. Umm, I guess he doesn't ask me personal questions , he asked me personal questions earlier not now. I yap. I call him "brother" as a joke, and he got annoyed. Then we talked about traveling, and he mentioned another girl in front of me. I got annoyed, and he was laughing. He asked me for my social media, but I don't use social media, lol, so he asked about my WhatsApp indirectly.

I said I don't give my number to strangers as a joke, lol. He said, "Let's talk; if it works, it works; if it doesn't, it doesn't. If it works, then we can talk on WhatsApp." πŸ’€ I annoyed him with another brother joke.

We were talking about the weather, then he went offline for a few minutes. I got annoyed πŸ’€, so I said it directly, lol. He replied to me after a few minutes. Then I said, "Continue your work; I'm going." πŸ’€ Then I ghosted him. I didn't, lol; I'm busy because of my exam, I told him afterwards. His profile says "long-term relationship." He asked me what I'm looking for? 😭
I said short term and he said he is looking for long term not casual type, he isn't interested in it. He never dated anyone. I don't know if it's true or not. He is a merchant navy guy. We have same age
