"Divorced" doesn't particularly matter to the Church, because it doesn't recognize civil divorce as ending a marriage. However, living in an unmarried or adulterous relationship and having children out of wedlock is definitely a moral problem.
THIS DOES NOT make her decision to put her child's survival ahead of her own any less heroic or praiseworthy. It simply makes the description "devout Catholic" meaningless. People like this lady, who are anti-abortion no matter what the cost to themselves, can come from any religious background or none at all.
Sheesh. I may be going out on a limb here, BUT I THINK SHE'S DONE HER PENANCE!
The living with a partner out of wedlock, however, is another story...
