Pump the brakes

I’ve recently been seeing this guy, it barely going to be a month. We text 24/7 and see each other every weekend, how do I tell him to pump the brakes? I like him so much but it’s becoming a little overwhelming.

I don’t want him to think I’m less interested but the fact that it hasn’t been a month.. it’s scaring me

Edit-

We talk every single day, every hour and every weekend we’re together. I feel like that’s too much when we’re not even in a relationship
