What's Love Got To Do-Got To Do With It?

" 'Brett's got a bull-fighter,' Mike said. 'But her Jew has gone away.'(pg 215)"

In this entire novel, it seems as if everyone loves everyone. No one stays on one significant other for very long. This is likely partly due to the amount of alcohol consumed throughout the book's entirety, but it strikes me as odd. Brett has been married, is getting a divorce only to get married to Mike right after, but she relly loves Jake, but then she falls in love with Romero. Who knows who else she's fallen in love with besides them. Also, Robert is married at the befinning, then moves on to Frances until he gets tired of her and falls for Brett, but then it is assumed that he went back to Frances. In the end, it leads me to question the definition of "love" in this book. Do any of the characters know what it rally means? I don't think so. I believe they know all about infatuation, which we see when Brett cannot take her eyes off of Romero and Robert can't be away from Brett. Really, it is somewhat like today in the sense that the word love is flung around like a dirty mop.
