The reason why he did this may be to attract your attention, or it may be that he also wanted to post such a post to Moments. In fact, I think that no matter what his purpose is, as long as you control your mood and don't be influenced by him, then whatever he posts has nothing to do with you. If you are influenced by him in everything and you relate everything about him to yourself, it proves that you have not given up on him and that you still care about him.
