Wow anon12, mine sounds so similar! An all or nothing guy. Works obsessively, can't stop eating foods he enjoys even when he's adamant about losing weight.
I have described his behaviour to him the next morning and he laughs it off and thinks I'm exaggerating. I think I might film him next time. I told him if he knew what I'd seen the night before he'd be embarrassed. He didn't seem bothered in the slightest.
Florence, I guess not. I think the label is simply a way for me to diagnose his problem so I can understand why he does it. If I don't know the reason, I can't come up with a solution. An ultimatum won't work because I'm not going to walk out on him because of a drinking problem and he knows that.
