DV or just an outburst?

Today my husband threatened to punch me in the face. I'll give some back-story so you understand the whole situation.

My husband has anger issues and extremely high anxiety with OCD. These issues extend from childhood and I knew them when I married him. I accept them.

I myself am bipolar 1. I am in meds that work pretty well, but still have flare ups sometimes. I can be very irritated, depressed, I can be in a super excited state with boundless energy and I can engage in spontaneous (and reckless) behavior. I won't sleep either and it's just something he lives with.

He has threatened to punch me in the face before, like "if you did that, I'd punch you in the face" or "I just want to punch you in the face". He has also talked about what he wants to do to the stupid general public. It's usually violent stuff.

In reality though, he controls himself very well. He might punch a wall or door or break something, but he's never laid a hand on me or others. Though he's not afraid to confront them.

We do engage in domestic discipline. I have past trauma and family stuff. I also have big emotions I don't know how to handle and when I'm in my moods it's almost impossible to get out of them on my own. So with my consent, he disciplines me but only in areas I've approved like my butt and thighs.

All that to say, there is a healthy way that benefits and resets both of us that can make me see reason if that's a problem.

So to the situation today. He and I have been food addicts. Me on and off, him really bad all the time. That and videogames or shopping is how he copes with his stress other than yelling about what he's upset about. He has asked and begged me multiple times to help him eat well, to not allow him to make bad decisions etc with food and shopping. He has heart failure but an amazing body at 6'7" with muscle and he's able to push through his symptoms and still be fairly active. He recently developed a new bad symptom. So yesterday I physically blocked the vehicle when he tried to go get fast food. He fought me on it but eventually let me make him dinner from home. Then today he told me he's going to go to the store to get food. Mind you our freezers are full of food along with our fridge and pantry. But if it's not something he feels like eating (or cooking) he just wants to go out.

We both agreed before that we need to just eat from home so we can stick to our budget. So when he said he was going to the store I said no, eat from home. He said no and we went back and forth so I said give me a list of good you want to shop for. He refused so I told him I would shut off his credit card. That's when he said if I did that and his card didn't work when he went to the store he would come home and punch me in the face for real. I have no right to bar him from his money. (He doesn't have access to our accounts by his choice because of how irresponsible he is with money).

His thoughts are that he will probably have a short life so he should get what he wants. But he was a food addict before the heart failure. There was always a reason he needed to get what he wanted whether food or shopping in general.

I need an outside perspective on this. I've never been scared of him. I just want for him to be healthy but I know ultimately I can't force him to. I'm just trying to do what he's told me he actually wants. Should I just back down? He always says he just wants to die after he gives in to not getting food and I feel like crap. He just seems to be getting more angry lately and... I'm not sure this time if he would actually punch me. He never had before...
