One year anniversary, haven't met yet.

How do I politely ask when we can meet in person. Daily chats, video calls every week, I know he is a real person, I have been with him one year. Early on our relationship, we talked about meeting in person but I live in the USA and he lives in Europe, so we both know it will take some time to save money to travel. But now it's been a year and I wonder how's the best approach to ask when we can meet.
