How do I tell him


So I’ve been dating this guy for about 6 months and we’ve been friends for 7 years and I’m totally in love with him. We are also in a long distance relationship me in the states and him in Europe. I go to visit him shortly and it’s getting harder and harder not to tell him in txt or over the phone that I love him I want to wait til we are face to face but I’m also nervous he won’t feel the same way. What should I do?
