#039 Respect their choices.
You don't have to agree with the choices they make in their life or decisions they make, but you have to respect them. If you're still early on in the relationship, you can lightly suggest something else, but you have no right to push for something they don't agree with. But if you're a little farther in your relationship, you're gonna have to talk about them eventually. Maybe you want to have children but you're Catholic and they're Jewish. You'll have to come to a decision about how to raise them religiously (if you want to at all) and it should be a mutual agreement. You there's something major that you think could make or break the relationship, you should bring it up early on. If you both can't deal with the way the other feels on a certain subject, then that's not a great base for a successful relationship.
