25F and 25M and I’m so confused

So I (25F) met a guy (25M) when I was vacationing in another state and he said he likes me and we started dating. It’s been 3 weeks idk if I should call it dating. I have a few issues idk if I’m overthinking but one major one is communication. He told me he’s not a texter and initially he texted a bit and video called but he goes missing all day. Like he texted if we can talk and 3 mins later I call and he’s gone and we text next morning then lol. That’s one, second now he’s busy with work that I understood but he doesn’t fucking text me all day. And then I called and he didn’t answer and then his friend sent me a video of him sitting with them. And everytime (4 times so far) I text him I’m sad or it’s not working out and he doesn’t talk etc he immediately calls says I’m sorry I love u, has a perfect excuse and he’ll keep calling me until I’m fine. But why should we have to go to that extreme. He confuses me a lot. I have deduced that he’s just all talk, he knows what to say to make me feel better but doesn’t act.
But idk if I’m overthinking or is he actually bad at texting and loves me. And idk if this make him emotionally detached. And it’s been 3 weeks only I can’t say for sure either
