But this is not likely to happen if she just does not like her husband too much or if she finds that she does not have too much compatibility and interest with her husband. The option of temporary marriage removes this unjust look of authority. In Temporary marriage a girl and a boy have opportunity to live together for sometime to find if they will see a good future for their permanent marriage. As I said, the couple entered in temporary marriage contract may put the condition at the time of contract that the marriage is not to be sexually consummated. The guardian of the girl can also enforce such condition and the couple can just visit each other during the day to talk, study, and take part in any other non-sexual activities.
Temporary marriage is a conditional marriage.
The purpose of such contract can be even only for talking to each other. Although necessary talks between two sexes in order to get along with daily life, without evil intention and without possible evil consequences, is not forbidden in Islam, but a man and woman who are presently unmarried and who are in close contact with each other due to the job, study or whatever, are encouraged to enter to such contract. This removes any possibility of sin. In another case, a boy and a girl may NOT have reached to a point to manage a family life with all financial and legal responsibilities. Or they might be able to manage it financially but they are in a temporary situation where they can't plan for permanent marriage, like bachelor students who come to other countries to study where they may not be able to find a good match for the permanent life in the foreign country as a result of cultural differences.
