AITA for not losing weight fast enough

My wife wants me to lose weight for her to get under 200lbs. I have already lost 30 pounds or so and am about 10 pounds left to go. She asks me to weigh myself everyday and if I say I don’t want to she gets upset with me. Even when I do and if it stays the same or goes up a pound she freaks out and says I’m not trying for her and I’m mentally abusing her for not giving her what she wants. I don’t know what else to do.
