What is the ruling on aborting a three-month-old fetus due to the imminent separation of the spouses and issues concerning the custody of their two previous children, in addition to circumstances related to the wife's father?

Aborting a fetus is forbidden at all stages, even before forty days, unless there is a fear for the mother's life because of it, based on the reports of trustworthy doctors. If the soul has been breathed into it, then aborting it becomes murder by consensus.
