Liu bei had three wives

It is a rumor that Cao Cao wanted a woman and he started a war just for her,which was fabricated just for romance or insulting Cao Cao.He was not Romeo and beauties were nothing in his heart.
And it was impossible that a prince fought for democracy then,220-265.Maybe what puzzled you very much is why Chinese disliked him and insulted him.
Because in the ancient China,one's origin was very important, unluckily his foe Liu was considered to be of noble origins.therefore,CaoCao ,whose Adoptive grand-father was an eunuch despised by scholars, was very undeserved who had to accept rumors from intellects.
