She wanted her life shaped now, immediately—and the decision must be made by some force—of love, of money, of unquestionable practicality—that was close at hand.
Daisy was ready to settle down and begin her adult life. However, due to Gatsby’s absence, she was caught in a conscious battle debating whether or not she was to wait for Gatsby to return, or move on. Being aware of Daisy’s marriage, one can conclude that Tom happened to be the one “close at hand”. He was wealthy and able to provide the lifestyle she was ready to live.
