Wow, my husband is from Costa Rica too. What a coincidence since it's such a small place.
Since his family is full of constant drama, if I had my tubes tied and we told them I think it would boil over quickly. Keep in mind he's the only male out of three sisters and the only one without kids, however he also left the country at 20 and they've sort of seem him as a traitor ever since getting citizenship. Basically one more thing wouldn't surprise them too much.
We're obviously different from the crowd so we try to just be who we are, and they will accept it or they won't. So far that has worked with all of our previous non-traditional announcements and he's still in the family and I'm still welcome in their houses.
