I am against using the word partner for calling your bonded other half. Mainly because when you hear the word partner in RL, everyone automatically assumes a buisness partner, and then there's an awkward silence as you explain what you mean by that.

No one is confused by the words husband or wife, which is why if we have a different word for calling your other half, it should be something entirely new or descriptive enough that people don't get tripped over what your using the word for.
