My crush never "likes" anything I post?

I feel silly asking about this, but I'm a millennial, so sadly, this has been bothering me: My crush "likes" everyone's Facebook posts/pictures except for mine. We have a lot of mutual friends, and I always see him "liking" their stuff. In person, he and I have a good relationship, no better or worse than the relationships he has with the other people. I don't doubt that he likes me as a person, but I'm confused as to why he would "like" everyone's posts, but not mine. Also I'm probably overthinking because I have a raging crush on him...
