In all fairness to the Church, her answer is more of "One cannot participate in an evil in order to prevent another evil." The ends don't justify the means, and that's a long standing Church teaching. This situtation does not qualify for the principle of double effect.
It doesn't make it any easier to live with it, but it goes a lot deeper than "suck it up." It's more like "Pick up you cross and follow Him."
Yeah, but why is artificial contraception evil? Just because something falls short of its fullness, doesn't mean it's evil. I am obedient but not convinced.
