LOL...I'm pretty sure "putting your foot down" is not going to win her "approval". I guess I'm just lucky when my wife and I where dating I only had one single ball python and she was never really against it and over the years we have BOTH gotten deeply involved with reptiles and she even has her own animals! I guess try and find out WHY she is against it, is she one of those who can't see past the myth's of "slimy snakes" or is there something else behind her argument? As much we men folk (well me anyways) hate to talk about stuff I think its the way to go. If she has a fear of snakes maybe you can help her get over it or offer to keep the animal someplace in the house she doesn't have to see it.

good luck LOL!!
