Good question. Women are NOT supposed to keep the rings in the first place!
what would be any legal reason preventing my fiance and I from living together
Any engagement ring law is usually this: If the male breaks the engagement, she may keep the ring. If the female breaks the engagement, she must return the ring. Oh, and in most cases I've heard of, it's not a "law" as in a specific legislative decree. More just the common practice of civil courts, who reason that the ring was given in expectation of marriage, so if she breaks it off, she "owes" it back, but if he changes his mind, that's not her fault. However, as with all legal matters, one should consult with a local attorney, more familiar with the laws of your state, and your specific situation.
Unless it is a family heirloom, then no the young woman does not need to give the ring back to her ex fiance. He gave it to her as a gift and it is hers. There is no reason he should want it back because if he met another woman and wanted to give her an engagement ring she would not appreciate getting a ring he had given his previous love.
In war, the rules of engagement refers to the "law" of attack. There are specific rules on when and for what reason the Military will be told to attack an enemy.
That might not be the best idea. Your parents have a reason to not want you to move in with him/her.

As long as you both are not talking privately there is no reason you cannot talk with him, but it would be wiser to walk away from this situation because he has feelings for you and is disrespecting your fiance because he is hoping he can win you over.
The only place I know of is Netflix, they have all the season to watch instantly. The reason they are most likely the only one (or the only one with good quality) is because Buffy was cancelled and most websites without breaks only tend to keep current shows.
