After all , while some happy couples are celebrating Valentine's Day this month , plenty of other people have more complicated relationships . This show is for them . Our first expression may sound impossible . “Love ” and “hate ” are opposites , but they are both strong emotions . In the case of a love-hate relationship , a couple just keeps going back and forth between the two feelings . One day they fight like cats and dogs . Another day they sing together like lovebirds . You can also have a love-hate relationship with something besides another person . If you love some parts about your work , but hate other parts of it , you can say you have a love-hate relationship with your job . Another expression that relates to opposing feelings is , “There is a fine line between love and hate .” A person can very easily go from loving to hating . These types of lovers want to be together , but everything seems to keep them apart – even the stars . This expression comes from the belief of some cultures that the stars control our futures . Probably the most famous star-crossed lovers are William Shakespeare's Romeo and Juliet . Star-crossed lovers never seem to get together . So they are rarely on the rebound . A rebound relationship is the first relationship someone has after he or she has ended a serious , long-term relationship . The term “rebound ” used in this way dates back at least to the 1830s . People on the rebound are easily hurt and vulnerable . So they often make bad decisions in choosing a new love interest . This time and distance alone to heal is not to be confused with a long-distance relationship . People in a long-distance relationship live very far apart from each other and don't see each other on a regular basis . A long-distance relationship can be perfect for someone who likes their own space . But it can be lonely for a person who wants to spend a lot of time day-to-day with their partner . A long-distance relationship can also be very expensive if the two people need to buy airplane tickets to see each other . Of course , every relationship has its ups and downs , good times and bad times . But a tumultuous relationship has very high ups and very low downs . Even though a tumultuous relationship can be troubled or even violent , it appeals to some people who like passion and drama . But after a while , all that passion and drama can destroy the soft , gentle feelings the couple had toward each other . They eat away at the couple's love like poison , and the relationship turns toxic . Now , let's talk about the couple who that can't seem to decide whether to commit . Sometimes they are together , sometimes they are not . A love triangle does not describe a person who loves geometry , but it does involve the number three . A love triangle describes three people who have feelings for each other but those feelings do not always match . So let's say Barry , Gary and Sherry all went to college together and are very close friends . However , what Sherry doesn't know is that Barry is deeply in love her . Meanwhile , she is in love with Gary . But Gary doesn't know about either of his friends ’ true feelings . He likes them both . What he really loves is baseball . One day , Sherry takes a chance . She tells Gary how she really feels about him . Gary is surprised … but then he realizes that he loves Sherry , too . To show her how special she is to him , he takes her to a baseball game . A television camera at the stadium catches them holding hands , and then kissing . When Barry sees his friends in a lip-lock on TV , he becomes very depressed . Now he is no longer in a love triangle . Now he is experiencing unrequited love . One person falls in love with another , but the feelings are not returned . That night , he runs through the rain to Sherry's house . He knocks on her door and , dripping wet , begs her to choose him over Gary . This is a bad decision . Sherry tells Barry that she does love him , but she's not in love with him . The two are very different . Sherry has just said the worst thing for someone in love to hear . Barry is crushed . He decides to move to New York City . He joins a rock band and sings about his broken heart . Do you have expressions that describe unsuccessful relationships in your language ?
