High Fidelity

The book I chose for the assignment to read a book that was later turned into a movie is High Fidelity by Nick Hornby. My smelly friend Anna recommended it to me, and told me she could lend it to me, and since i don't like checking out books at the library because i'm usually a slow reader, it seemed like my best option.
The book starts out with the main character, Robert Fleming, going through all his past relationships and analyzing them and what went wrong. They all lead up to his most recent relationship of 2 years with a woman named Laura, that just came to an end. Rob soon figures out that she had been having an affair with the guy named Ian that lived in the apartment directly above them.
Rob owns and works at a record store that isn't very successful. The two other men that work there are named Dick and Barry, they're both socially awkward music junkies. They take rob out to a show one night just to try and cheer him up a bit. He starts to fall for the singer that plays that night named Marie Lasalle, who invites them to her next show out of town.
All of the record store boys split a cab and go to her next show. Marie is singing with a guy named T-bone and Rob gets upset and leaves the show alone.
Then there's a flashback to Rob and Laura's relationship. Rob cheated on Laura for a week while she was pregnant which was a main reason she got an abortion. Rob's record store started to go under and Laura lent him a few thousand dollars, which he has still not paid back to her.

That's as much as I've read so far.
So far the book is really depressing. Rob doesn't know what to do with himself and his only comfort is in hope of finding another girl to put all his time and effort into. Also his life is just kind of dull, he has no real goals or anything going on with him besides a sad break-up and a failing buisness, and it seems like it isn't even a rough patch in his life, it seems more like his life story.
