>1. If I leave, is it okay to still visit whenever I want, or are you strict about that? Leave Earth you mean? That depends on where you move to. Different species and places have different privileges. There is no general policy for this. Your level of interaction with a foreign planet is determined by the relations between your home world and said planet.
>2. Is it ok for a non-human to take a human wife? Why would a non-human want a human wife? Humans are disgusting, I don't think, in the history or this planet, that such a thing ever happened.
If you are referring to humanoids, this is a different matter. As long as it has two legs, arms and stuff it works. Or any number of them, but you get the idea. Humans are only used for genetic experiments when abducted, no one wants to have them as wives. Men get taken to "extract" genetic material so maybe you can have an alien "wife" if you're a male human, but the reverse doesn't happen. That would be, from the view of the other race, like incarnating your children to be slaves. No one does that.
