How to reduce anxiety with texting

So I’ve been seeing this guy and we don’t always talk consistently. It’s kind of early stages and we’re also long distance.

But sometimes he texts me back in the middle of the night. I subconsciously in the middle of the night wake up and check my phone.

I’m noticing I’m loosing good sleep over it.

I’m thinking every night I need to start turning off text message conversations. So I don’t have anxiety when I’m sleeping.

Do you think this is a good idea? Or any advice on what I could do instead?
