He rejected me when I confessed to him. But we are still friends like we used to be. It's just that I feel highly uncomfortable now that he flirts with me as he used to. I don't have feelings for him, but I don't want him to flirt with me as it puts me into a really awkward situation. But asking him to not flirt with me will make the situation a thousand times awkward. What should I do? I still want to be his friend, but I don't want him to flirt with me anymore.
