Should I talk to him like nothing happen?

Yesterday, he saw a bad side of me. When I get stressed and I don't want to talk about anything but yet I do. I told him I'm worried that he is leading me on and he clarified that he isn't and he does want us to happen, but if I am reserved it will be hard. I am honestly embarrassed and don't want to talk to him. He said everything was fine but, I don't know why I don't want to talk to him. I haven't replied to any messages, I'm just really embarrassed and want to step away. He saw a bad side of me that I did not want him to see.
