Hey viktor,
I'm not sure if he wants to break up or not. It sounds like he might but maybe he's doing the whole "get them to fight for me thing"? Idk, it's weird.
Either way it doesn't really sound like it's you, i think he may need to work on himself and be happy with himself. That's not a problem you or anyone else can do for him.
He does say you wear him out and while that may be more reflective of him, id at least give him some space while he sorts stuff out. Maybe call it a break while he figures stuff out, meanwhile don't feel obligated to wait for him.
They also have those storage/riser blocks that raise the washing machine/ dryer by 1.5ft or so. Check with the manufacturer. Those might be able to help push it out of arms reach. Not the only solution needed but could be an extra layer of defense, and saves your back!
Also you say you keep the door closed, but just an fyi that the door is supposed to be able to air out after a load or you can get a nasty smell eventually and give off a musty smell to clothes.
I know that's a new problem but if you can somehow limit access to the room then that takes care of both issues.
