Would you keep the baby?

39yo pregnant with 5th child. Already have 2 in college and 2 in elementary. The father acts as if he wants to keep the child but the relationship between the mother is strained. She believes he planned this regardless of her not wanting anymore children. No they were not using protection as he would discard or become ignorant if she took or even discussed prevention. Neither are fiscally able to take care of a new child as it stands today. Neither want to bring a child into this crazy world. He really wants the baby even with knowledge of the obstacles.
