He stopped communicating with me on social media and stopped liking my photos after I declined to go out with him?

Does he think I don't like him just because I didn't go out with him? I was just caught off guard when he asked and wasn't prepared to go hang out at that time. He has definitely changed his pattern in communicating with me. It's almost like he completely ignores my post and photos at this point. I will say he is very popular not sure if that can help shed light on things.
