I can't, she cheats.You can put her in a castle and play Tablut with her three times a day. Whenever you win there is a high chance of gaining relation with her.

I have about -40 relation with my wife, I'm convinced she's bore me at least 3 offspring that aren't mine out of spite
I got a lot of negative relationships with everyone but few good relationships, and i can't find a way to gain realtionships quickly
