Is it permissible for a pregnant woman with a daughter to seek divorce due to the husband's shortcomings as a father and a husband, and his desire to marry while claiming he lacks money for expenses?

There is no harm in a wife seeking divorce if the husband is derelict in her rights, such as maintenance and conjugal relations. However, if he wishes to take another wife, she is not permitted to seek divorce, unless he is unable to deal justly between wives, in which case he is not permitted to practice polygyny.
