Giving up on my marriage

We've been together for a little over 10yrs married for 3, ten year age gap ( im 32 he's 42) Honestly it's become so draining and confusing. He has always been constantly sick and ive been there for him through his sicknesses and accidents. He doesn't like doctors so I've been the one to heal him through home remedies and alot of tlc. But I've noticed that when i get sick i still cook, clean, take care of the my kids (i have 3 from previous marriage, he has 2) and our 6 dogs (at one point) mind you i work 12hrs. I'm mentally and physically exhausted! He has the audacity to tell me what do i do all day? That i need to manage my time better and put him first. I don't have social media for the same reason i need to focus on keeping my household clean and undercontrol. For me his words were more hurtful than ever before! I've put this man first so many times and he just never appreciates anything. All this situation has caused me to fall into a depression. I've tried talking to him and things are good for a few days then back to the same bs. I feel we're wasting our time. I feel so sad to think this would be my second failed marriage😔😭
