Thanks to everyone who has replied so far. Yes, I think control has a lot to do with this, as does her insecurity about her beauty/physique. She has gained some weight since marriage, but I have consistently told her that I think she is beautiful. And I do.
I face an uphill battle, convincing myself to stop being the victim here, to stand up for what I believe, and to take care of myself. I am finding strength in the stories of others on this board.
