I need advice.

I met this guy on a chat/hangout app. We talk almost everyday/ sometimes on the phone for about 3 weeks now. He’s really sweet to me. Every time we video chat I get so nervous I don’t know what to say. He’s coming to meet me in January or February in person, and I really like him and I want to see where it goes in the future. I just hope in the end he feels the same way. Am I rushing? Because I’m trying so hard to take it slow. Recently he told me he has exams coming up and he apologized to me that we might not always message each other. I told him it was fine and that he should focus on his exams. He’s 23 years old from Hong Kong and I’m 21 years old from America. I told him that my dad wants to meet him, he sounded happy. I just hope this guy is legit but I’ll never know unless I meet him in person. :/
