Divorce? Got pregnant by a married man. What can I say, I was in a hurry! (Legacy Challenge) He moved in with me, but he can't propose. I hovered over all of the houses and couldn't find where she lived. Finally, he called her enough and she agreed to come over. Well, we woohooed while she was there and she got mad and left. But they're still married! How can I get them divorced?
Go to the lot where the husband and wife live. If their relationship is low enough, there should be an option in the pie menu called Break Up. I think it'll be in under the Fight option, but I'm not sure.
