This may be somewhat morbid, but it's all in good fun.

What I mean is, is there someone who marries someone only to kill them awhile later and trap their soul in a gem and then lock it away in a drawer somewhere in your house?

A regular Wife/Husband Collector.

No, I prefer to pickpocket the clothes off my wife and have her walk about in her underwear. Then I fill a chest or cart with cabbage.

I prefer to murder them in my home and see if thee bodies go away and if my new spouse will mind my ex spouses corpse.

This may interest you,
