A Big Grandpa Hug to you....and maybe some thoughts too.
You are the one who feel the abuse.....you are the one who clean it all up....you are the one that yell and yell but that put no "force" behind the yell.
You must take a time out for yourself.....you must try to figure out clear rules for both your kid and for your Partner.
Those rules you have to fight for....they might hurt all in the start....you are fighting for some respect...they are fighting for loosing of freedom...in the end I hope you win.
It must be clear that you must not put up rules that might be moved by the other part...if so are done...you will only get more fight.
You might start by putting together a family meeting once or twice in the week.....where you all discuss how every normal task shall be done....try to include all....but have a strategy so they don't manage to transfer all back to you.
Tell them that they in the end all will benefit from it...the harmony will be greater...and they all learn that to run a home takes a lot of work...and that it is wrong to depend on one person to do it all.
Another big Grandpa hug and Good luck
