Need help

I’ve been dating a guy for 3 months. He went on vacation with his buddies for 4 days. He comes back today. But during his vacation he only text me the morning of his flight and when he arrived to his destination. Then on Sunday he text me back when I text him asking him how his vaca was going. I didn’t want to text him a lot. I know he’s on vacation and he’s not going to be texting me. But he didn’t text me not once other than those times. Am I wrong for expecting at least one text from him ? I have so much anxiety behind him coming back. I keep thinking what if he got used to not texting me or his feelings changed and he decides he’s ok with not seeing me. I’m very nervous idk why.
