Chinese students who are born after 1990 never learned about Chinese grammar. So I would like to explain the sentence 你没喜欢过他。 in this way. Tom, Alice and I are close friend. T cared about A very much, just like A' elder brother. Later, T falls in love with Gina. A was really sad after hearing that and cried to me 'He is a L'arnacoeur!!!'. 'He did cares about you, A. However, there are 'cares' and 'cares'. I am soory, but 他没喜欢过你'. You can image another situation to say 你没喜欢过他.
