There may not be two possibilities for this. First, if there are some contradictions between you, and you find that the original greeting signature has been deleted, it only means that he may still be angry. Can't say he doesn't love you. It's not that serious. You may think too much. Second, if you delete the signature, he may not need to change it, because our signatures don't always change, do they? On the bright side, the boy deleted the original greeting signature, which can only temporarily show that he is not very happy now, and can not show that he does not love you.
