Advice on keeping up with housework please

I am desperate here, I have always struggled massively with keeping my home tidy, ill get into a routine for at absolute max a month and then find im burnt out and cant get on top of things for like a year.

I was diagnosed with adhd primarily innatentive, last year around june, Ive got 2 kids and an amazingly understanding partner who also has adhd but its getting on top if him that hes constantly having to pick up when im burnt out. To the point it is now affecting our relationship, we are due to get married in September and I love this man with all my heart and it hurts that im causing him stress and over something as simple as just keeping the house tidy.

Any hacks or routines that you've found actually help please let me know! I will try anything at this point.
