Is it too early to ask a guy I've gone on a few dates to celebrate my birthday?

I'm seeing a guy for one month and we've gone on three dates. We went on a hike and spent the whole day together on our last date. He said he had a great time with me and we continued texting each other afterwards.

My birthday is coming up in a few days and I texted him saying that I'd like to have dinner with him sometime soon because my birthday is happening soon. I also said that it wouldn't have to be fancy or anything special.

I haven't heard back from him in a day and I wonder if that was too early to ask him given we are not exclusive or anything. I know he is still using dating apps.

That said, if he backs out at this point, I think he is not that into me anyway. Any thoughts?
