I really liked MeSo's name until my DH started calling her mesothelioma. I've asked him several times to stop calling her that, but he is very stubborn. He never calls her by name, just makes up stupid names and calls her whatever. I'm not sure if its because he can't remember her name or just doesn't like it.
Any suggestions? I'm so frustrated and angry at him for not using her name I'd like to strangle him (don't worry, I won't). But I do think I need to find another name that he can't mangle. Help.
