What should i do?

I’ve been talking to a guy for a few months now, but at first, I thought it would just be a friendship. We haven’t met in person yet, but we were planning to meet this month. The problem is that I’m a bit nervous because he doesn’t know I have vitiligo. It’s not something I’m ashamed of, but I think some people find it unusual. It’s not like, “I need to tell you I lied about my appearance”, it just didn’t show up in the photos I took. Do you guys think this could be a dealbreaker? Sorry if I didn’t express myself well, I’m using a translator.
