My Answer- She flirts w/ other men + Lennie is interested; Curley might find out; Curley will find any reason to fight w/ Lennie.

Why does Curley want to fight Lennie?
because Curly does not like big guys since he himself is on the small side. You'll notice that Curly does not pick a fight with George because George also is not a big man
