I'm having a similar problem. I married Senna and moved to Lakeview Manor. Right now, whenever I select her, she simply says "You and I are the only ones in Skyrim worth loving." and then walks away. I cannot open a dialog to buy or sell, or interact in any other way. This seemed to have happened some time after she was kidnapped by bandits and I had to rescue her. That was 3 days ago and I've played several hours and quests since then and I'm not sure what's causing it. I most recently became head of the thieve's guild as well. Any ideas? I guess I can live with things the way they are. I can live without home-cooked meals and she doesn't buy or sell much anyway. It's just one of those bugs that drives me crazy.
