Best way to ask?...

So I’ve been dating the same guy since July of 2019. We go out every weekend and he even comes to my house at least once during the week and stays with me. We haven’t yet established what we are.

I don’t know how to ask what we are. I’m scared it will ruin whatever we are doing. I do like him a lot but I’m scared we are just wasting each others time.

What is the best way to bring this up in conversation and ask him?
