How to tell the person you’re seeing you stutter?

How to tell the person you’re seeing you stutter? I’ve been talking to this guy for couple months now and he doesn’t know I have a stutter. We’ve talked on the phone like 2 times and we mostly text. I’m highly insecure about my speech and I just don’t know how to tell him since I’ve dragged this for months now. This is a long distance “relationship” and he wants to meet me in couple week and I’m very nervous about it. I also have really bad anxiety which makes everything worse. Any advice on how to bring the subject up?
