I'm wondering if your husband has undergone some personality changes? It's highly abnormal to say, "You do ____ better than Martha." It sounds like he's acting very impulsively, that he has a lot of anger, and is not "himself." Has he always acted impulsively and had anger issues?
How long have you been married? I'd seriously consider leaving - It sounds like he doesn't care much for your feelings. Trust me, Little Miss Hotstuff will get the same shaft and head out of town if she has a brain in her head, and if he's this rushed and impulsive, in five years, he won't even remember her face.
