Non Adhd Spouse Vent

Hi all, I'm hoping that I can release some emotions on here as I'm at my last straw. I (non adhd) am a wife to an adhd spouse, and I am exhausted, I am in burnout and recently started antidepressants and counseling for myself. Something which I never wanted to do but I broke and finally admitted I needed help.

My husband is a good guy but he has the hyper side of ADHD, and it is exhausting, I feel like I married a toddler. 

I literally do everything, the house chores, the bills, the presents, the laundry, the food shopping, the cooking, everything! My husband keeps saying that I do too much but he doesn't help, or when he offers it's an empty gesture or (and i really appreciate how hard it is) his ADHD just wont allow him. I have tried approaching him in different ways to get him to help, explained how much the mental load it taking on me, how I need a tidy house or it really sets off my anxiety, I have suggested selected chores, timers, reminders, everything! But he either wont try them (then says I'm an arse for suggesting them coz he cant help it) or it happens for a week then that's it. He says i ask him at the wrong times, so I dont ask him on the evening now, I ask him just before tea (but then im telling him what to do) or I will ask him on a morning, but i'm being a nag. He has tried to step up and help but like I said it doesnt last.

I may sound like a right a******e but how is this fair? 

Is anyone else's adhd spouse quick to point the blame to anyone else? like he'll make a mistake (even small ones) and whilst I don't lose my temper or make any comments, he'll end up blaming me for it. 

I have had countless people come up to me and say you have a patience of a saint and all he has to say about me is negative.... 

I just cant keep going and I need to know is this normal for adhd relationships?
