Need advice 😩

So I've been talking to this guy and I really like him and were getting to know each other taking it slow but for some reason I am so shy around him. And obviously it's cause I really like him n stuff but he was telling me that I need to talk more cause I'm really shy and I get that because I'm usually so talkitive and more outgoing , he's just one of those really good looking guys that I'm surprised he even talks to me at all because he's just so good looking lol and idk I just don't wanna lose that him over me being so quiet what should i do or what do you guys think it is.?
