We'll Always Have Summer
In the book We'll Always Have Summer by Jenny Han, the main character Belly is torn between two guys. One is named Jeremiah and the other is named Conrad, they are brothers. Belly and Jeremiah get engaged after Belly's first year of collage. Both there families do not approve, especially Conrad, who after two years is still in love with Belly. Belly is not a strong character, and lets her whole lives be run by boys.
One way that Belly lets her life be run by boys is how she doesn't care if this wedding ruins her entire life, she just wants to be married to a boy she's not sure she's in love with. For example Belly's mom who she is incredibly close to does not approve of this wedding. But Belly goes against everything her mom says, moves out and plows through like its a race, leaving her whole family behind in the dust.
The last example that Belly lets her life be run by boys is how after everything that Belly put her family through she decides that she doesn't want to marry Jeremiah, she wants to merry Conrad, therefore having to put her family through double the stress.
