Relationship advice

So i met this guy and on paper he's perfect. He's the most caring, honest and wholesome person I've ever met. I don't know when was the last time I was able to talk so deeply and openly with someone, we also have very similar interests and values. But for some reason the way that he's acting somewhat puts me off. It's like I find him somewhat cringey? And I feel awful about it! I really wish that I could just like him and be endeared by him but I'm just not. When we're talking about deeper topics I'm absolutely impressed by him, but when it comes to day to day banter: I can have a great time talking with him and laughing, but then he says/does something that makes me cringe and I feel guilty about it. And I really want him to have someone who just loves him for who he is. So now I'm scared of losing this relationship as well as scared that if I were to date him, I would hurt him by not loving him strong enough/having to break up.
