Inclusivity?

You can just set your own labels under the new relationship menu. Whatever you prefer can go there.

It's def not a bug.

You misremember. It is possible to specify custom pronouns but for relationships you are stuck with what they now feel that you should refer to your wife/husband as. I don't understand why they didn't just add Spouse to the relationship dropdown in the name of inclusion instead of deliberately choosing to exclude everyone that would prefer they could still call their wife their wife and their husband their husband. But you are right since it was done deliberately it definitely is not a bug so belongs in feedback.

I was referring to the custom relationship label but I haven't really tried it out. Seems both of the relationships show in the profile so it's not really replacing it.

Still not a bug though and something for the feedback forum.

Thank you for pointing out this feature, I have yet to come across it. Is this custom relationship label part of the Lovestruck pack? Or was it added in the general game update? I have everything up to horse ranch and I'd rather not put more money into the game just to get my husband back to my husband... I hoped it was a bug because I just figured with them advertising inclusivity it wouldn't have been at the expense of others inclusion in the game. 

I thought it was added to base game but I'm not 100% certain.
